I have to agree with others on the 100mg being simply too strong in nic/smoke juice. My smoke juice/nic-juice is only 60mg in large bottle though at this moment I can't recall the exact size. I always wear gloves! I also wear safety glasses as a precaution but this is part due to the nicotine liquid being dangerous and the fact I'm legally blind with minimal light perception. It makes it difficult to see how I am mixing my liquids.
As a general rule, I purchase my flavored liquids from MFS and include the extra-flavoring/double flavoring in mostly non-tobacco flavors though I do have a few smaller bottles of tobacco flavors. I buy my e-liquids pre-mixed in lower milligrams then I transfer to a separate, larger bottle in order to add a bit more nicotine to the liquid.
I keep two bottles of e-liquids. One is marked with small felt letters (stick-on kind for the blind) in order to tell the difference btw bottles. The second bottle is one where I add the small felt letters and an additional bump dot (like a braille dot only I buy the bump dots a little larger b/c of the nerve damage in my hands and fingers. It's easier for me to feel the felt letters and bump dot. The bottle with the bump dot is the one where I've added a higher dose of nicotine/smoke juice. This bottle is one I use at the highest cravings of the day such as when I wake up, after meals, and before bed then there are times when I am under a lot of stress. I used to smoke more than I was stressed out; now I simply vape more when I'm stressed out and it works, esp with the higher nic doses in the e-liquid.
The liquids at MFS (My Freedom Smokes) is more than economical if you don't want or like the double/extra flavoring. If that's the case, you can actually add more smoke juice and PG/VG or a combination between the two to stretch the e-liquid to last longer. There are all kinds of ways to save money with e-cigs. I was spending approximately $300+/- each month on tobacco cigarettes (analogs). Today, I spend on avg approximately $30-40 a month, if even that b/c it includes the need for new atomizers, cartridges, and replacement syringes to fill the carts. There is also the cost of the polyfill I use to repack my cartridges with but the bag I have has made it through almost a year & it looks as if it's barely been touched. Thanks to the kindness of many suppliers, I receive some sample flavors with my order, which allows 2 things to happen: 1) I get extra e-liquid for use if I run short and 2) it gives me a chance to try out a new e-liquid. If I like it, and there have been only a limited few I haven't cared for over the last 1+yr, I will purchase a larger bottle to keep with my stock as I rotate out my flavored e-liquid. It's how I came to love Peach flavor, Sweet Apple, Coffee Flavor, Banana Cream, etc... I even like the Dr. Pepper flavor but for the life of me I can't bring myself to buy one of the meal-type liquids such as roast beef, chicken, etc... I'd love to try one but to buy it without tasting it, I don't think I could do it.
In addition to this process, it gives me material to use when working on my blogs and writing for various media outlets both online in the digital age as well as in book/newspaper format and even magazines (most are in large print, Braille, cassette, and/or digital format as the primary mags I write for are for the blind. E-cigs are the best thing since sliced bread for the blind. I'm not burning anything by accident; I don't lose my cigarette in the ashtray, no more small holes in my clothes from the small burning bits of tobacco & paper. The GREATEST change is the loss of the smoker's cough & not sounding like I have a box of Rice Krispy Cereal with a gallon of milk in my chest and lungs. I lost the cough & Snap, Crackle, & Pop within less than a month after I began vaping on July 7th, 2010! My doctor is ecstatic with the results & my DH has stopped his #$%%^ griping, & moaning over my smoking in the house since I switched to e-cigs. He's actually been supportive, which is out of character for him on this level. He's always there in a crunch and in times of life or death, or even illness but to be supportive of my switching e-cigs from analogs, I never thought I'd hear the end of it with regards to smoking but he can't smell the liquid unless he's very close to me. Otherwise, he doesn't notice it. My friends do though. They say my house smells like candies and fruits but that's likely because my favorites e-liquids are mostly fruits and candy flavors.
BTW: You do need to store your liquids in a cool, dry, dark place so they can last longer. I keep mine in a wine cabinet we've had for some time. It's cool but not cold and it has a dark glass on the door. It only holds about 3-5 wine/champagne bottles but I keep some space in there for my e-liquids and so far, they have kept fresh as the day I bought them. It's also prudent to not break the seal on a bottle of e-liquid until you are ready to use it. Oxygen is as dangerous at reducing flavors in e-liquids as it is to losing flavors of fine wines.
Hope this helps...
