Eliminate ONE thing at a time to determine where the issue lies.
1- Try ZERO mg juice (no nicotine at all)
2- Try high-PG
3- Try high VG
4- Try unflavored
Unless you are willing to test ALL OF THE ABOVE IN ORDER, then there is nothing anyone can do to help you from there. Randomly deciding to try this, then that will eventually get your answer (maybe), but it would be a journey no one can help you with.
^Sage advice.
I do have some zero mg juice that I will eventually put into my tank but not today or probably not tomorrow...but soon. That should be a good indicator to go onto VG juice or not true or false ?
Today I vaped Turkish Tobacco 6mg by Halo. That is the juice that sold me on E-Cigs but at 12mg. It is also the juice that I first used after returning home from a 3 week trip while smoking at least a 1/2 pack (Marlboro Lights) daily. I was floored by the results. It is not uncommon for me to continue smoking for a good week or more when I return from these trips. The E-Cig KILLED any need for another cig..again floored.
I then moved onto Longhorn by Halo. I love it and is easily the favorite of what I've been able to try so far. No issues at all to my knowledge and I was becoming close friends with it. It wasn't until I started this thread that I had a hunch about any side effects. I thought maybe I over did it THAT day since I had no issues before. Been using at least 3 juices Longhorn , Turkish Tobacco , Capt. Jack all by Halo.
I have a trip coming up and I know for sure that I will make a grab for a stinky. I hope to get this all figured out so I can take my E-Cig instead.
I initially purchased a Halo Triton then got all excited and purchased a Innokin iTaste134 mini which is what I was using today at 8ohm. At least I can use it for hash oil (MMJ) if all goes south
Nicotine and VG are separate issues. VG is what provides the majority of the vapor in ECigs, and is easily their safest ingredient.
If the 0-Nic juice doesn't give you spells, then Nicotine was the problem. If the 0-Nic juice still makes you ill, then there is much more at work here.
A smoker generally looks for 3 things from vaping, which it's 3 primary ingredients offer:
-VG gives you vapor.
-PG gives you that "sting" or "throat-hit" in the back of your throat, while also carrying most of the vaporized flavor.
-Flavorings role is self-evident.
*There are other ingredients which different makers add for different reasons. Not too many people have publicized problems with anything specific that I'm aware of.
The only reason I asked about flavors is to see if there is a common thread between your juices. Halo is a pretty solid company, and they aren't using Diacetyl, so all is OK there.
However, ALL the flavorings you're vaping are Halo tobaccos. This leaves only 2 possibilities for your symptoms:
1) You are sensitive/allergic to an ingredient in Halo's Master Tobacco-Base, or one of their constituent flavorings they purchase from flavor houses.
It doesn't sound like you're PG intolerant. But they might be using Ethyl Maltol, Acetyl Pyrazine, or a number of other "flavor enhancers" which might affect you. It's a longshot, but allergies could be at play.
2) You are seriously overestimating your Nicotine tolerance, and even vaping 6mg/mL is knocking you on your ....
A half a pack of Marlboro Lights is about 10-20mg Nicotine daily. (Roughly 1-2mg per stick, post-combustion.)
A 12mg juice COULD be a problem for some folks if they knock out 7-10 deep toots in 10-15 minutes, or thereabouts. That could blow through a mL of juice (dependent on device & atty), and pass the full 12mg to the vaper in that 15 min period.
But a 6mg/mL juice? Hmmm. Shouldn't be a problem, but that depends on how much/long/deep the draws were. If you haven't had Nicotine in a week or 2, then take 2 fast, deep draws on 6mg juice it might make you woozy. Especially on an empty stomach, or early in the AM.
First, knock out the Nic. Then take it from there. That's most often the cause of your symptoms. The key is staying away from the real deal.
*You say you used an iTaste 134 mini with a .8 Ohm atomizer? What kind of atomizer? How is it firing? According to Innokin, the minimum load for the 134 mini is 1.2 Ohms. What's with that?
