I started vaping about 2 months ago, using 12mg liquid from the start. I had previously been a smoker for several years, and right before I made the switch I was smoking about a pack a day. I basically quit cigarrettes right away, having one with friends maybe 5 times since. Recently (in the past 2 weeks) I have been feeling very shaky, and the only change I have made is switching from smoking to vaping. I thought if this was from a nicotine content that was too high I would have noticed this from the start. Has anyone else experienced this?
Many vapers do still go through withdraw after quitting tobacco. There are hundreds of other chemicals you're now depriving your body of that vaping doesn't provide. There has been research showing that TSNA's (Tobacco-Specific Nitrosamines) in conjunction with nicotine and other chemicals in tobacco make quite a potent stew.
That could be part of your issue.
It seems that as your body detoxes, your dependency on nicotine drops... pretty quickly at first for most of us. I started on 24mg, and quickly dropped to 18 within a few months, then to 12 where I lingered for a good 6-8 months. I'm currently bouncing around between 0mg for most of the day with times of 6mg just for a little bump.
I'm not opposed to the nicotine either... Technically, it isn't as dangerous as the ANTZ would like you to think it is! More children and adolescents have died from caffeine in energy drinks than from nicotine. Actually, I don't think anyone has died directly from nicotine poisoning, but I could be wrong.
The nicotine does have a great therapeutic effect on most of us. It's the only known stimulant that actually has a calming effect!
And as zoiD said... Water, water, water! Keep hydrated! Very important!
Over time, your body will adjust.
Oh... and I almost forgot this magic elixer...
Whole Tobacco Alkaloid WTA Eliquid Ejuice just in case you never heard of it. It has helped many a basket case get a handle on their withdrawals!
(I was one of them!)
