Heart palpitations (rapid heart rate and pounding) after quitting ?

Hey guys.

I quit vaping about 4 days ago now. For background, I smoked for 11 years, for 10 years I was smoking tobacco and then for the last year I’ve been using a vape (and heavily using it at that). Last week I started a new amazing job and I am fed up having to miss times of the day to sneak out for a vape. I quit cold turkey! I have found the cravings absolutely minimal in terms of wanting to vape, however, the physical and mental withdrawals have been INSANE.

The scariest one has been my heart has been racing and pounding for about 3 days straight ? I’m curious to see if anyone else has had this and might know what it is ? I went to the doctor today who had a listen to my heart and also did an ECG and confirmed everything is absolutely fine with my heart, and my pulse is only a little bit higher than usual. He recommended nicorette which I don’t want to do, I want to be fully away from nicotine.

Anyway other withdrawals I’ve had is insomnia, HUGE ANXIETY and some depressive moments, loads of crying (I don’t cry ever lol so this is crazy). The heart rate increasing has me baffled. Anyone else experienced this ?

Also well done everyone for quitting. We got this!
