Tense muscles?

[taz3cat]

Nicotine increases your levels of acetylcholine - the main neurotransmitter for activating muscles! Also I read that it can increase levels of lactic acid. This could cause both fatigue and soreness! I experienced it at first but am now tolerant of high levels of nicotine so I rarely feel it anymore.

I know this is a silly question but, did you use to smoke real cigarettes.

We don't get as much nic with the e-cig as you think.

It is more than likely a build up of lactic acid, I don't recall if pg or vg causes it more. Make sure you drink more water before going to bed and that should help. After a couple weeks my body adjusted and I don't have any issues any longer.

I have some bad muscle, tendon and ligament issues normally. I have actually noticed that the problems and flare ups are actually better than they were since I started vaping.

I agree, if it keeps on, see your doc about it.
