@Silent Scream:
Oh dear, you really do not have an easy time switching from smoking to vaping! Let me give you a big hug!
As many here have said, panic attacks can be a side effect of smoking cessation
(lots of cases) because your body misses some chemicals that were in tobacco cigarettes but are not in liquids. As in: withdrawal symptoms for that stuff.
(I myself had the opposite: extreme fatigue and a feeling of not being able to think or to do anything, accompanied by a feeling of being cranky and "just not myself", like the feeling when you are coming down with something).
Some vapers from the German forum have also reported all kinds of nasty side-effects of smoking cessation. Not vaping. Smoking cessation.
OR they can be a symptom of an underlying condition that was masked / self-medicated by smoking.
And yes, smoking cessation can also play havoc on an underlying / not diagnosed thyroid problem.
I would also recommend getting some of those WTA liquids (sorry, no idea where to get them in Europe) AND going to see a doctor to make sure it is not an underlying condition. And do mention the
smoking cessation.
I wish you all the best, and I hope that those nasty symptoms will disappear soon!
Hugs
Anja
