Something to keep in mind when working with the e-liquids is that nicotine is a poison. In it's pure form (from what I have read) one drop could kill a small child. Don't be alarmed, remember math class, you are likely looking at 2.4% compared to the 100% I just referenced (would need to ask a DIY for the real number). So remember to be safe, wear gloves to clean up spills or keep something between your skin and the liquid whenever possible. Wash your hands if any get on them.
I laugh as I type this, before I was disabled I was a mechanic and you could not imagine the things my hands have been in. I washed engine parts in gas or diesel while smoking lol, I have had chemical burns to my hands so many times I could not start to count them, but I have also experienced the side effects too. Now older, hopefully wiser, I do not subject myself to these unnecessary hazards, I try to be a little more informed now and follow a few safety guidelines. I have a 24 year old daughter in college and needs moral support and a 16 year old boy that needs a kick in the ___ (insert word of choice) from time to time, so I need to stick around a little longer.
Just popped into my head, something I read not long ago.... if you are like me and new to vaping, there is a possibility that you are vaping incorrectly (I likely am). If you are drawing on your tank like it is a cigarette or vaping at to high a voltage, you could be pulling juice droplets into your mouth or throat and that would cause the TH as well. From what I have read, hopefully someone will correct me. We want a soft even draw lasting between 3 and 4 seconds, nothing hard like a cigarette or straw.
Another thing is hydration, while I have read many people say to drink plenty water when vaping, I personally find that my coffee or a hot tea from time to time helps as well... even eating chips seems to stimulate the (mine anyway) mucus membranes and help keep my mouth and throat moist. I have yet to understand how I can inhale a vapor and it cause dryness but it does.
Yadda yadda yadda... there I go long winded again. There is just so much to learn, but it is much like riding a bike. You don't climb on a 15 speed mountain bike and head out on the Shenandoah Trail the first try, need them training wheels and guidance first... That is why I am on this site, I need my guidance because I broke my training wheels the first day
Anyway, I best stop before this is offered in hardback. Hope everything is working out well for you. You are on a great site with a lot of knowledgeable folks that are more than happy to help.
