So I took up vaping around 6 months ago... when I started I vaped a 0 nic then went from 3nic, to 6nic, to 12 nic, and then all the way up to 24 nic (at a very low wattage that high) at first I didn't have any problems and could hit my vape on 50 watts with 6 or 12 nic and could go run a mile feeling great and in great shape... then I noticed the more I did after about 3 or 4 months I started having problems at this time I was vaping at 24 nic running on about 5watts... workouts became harder and harder, I became more fatigued than I use to be and I noticed that I became very sensitive to vape... one time I think I got nicotine poisoning and had a panic attack my heart was racing it felt hard to breathe and I almost went to the hospital cuz I was dying lol... but before that I'd like to get really buzzed like get almost naseously dizzy but it'd go away after 10 seconds and then I felt like I was up on the clouds... I'd had very mild nic poisoning before but now after 3-4 months in I was having problems with vape in general I cut back majority and went from 24nic to 6nic to 3nic but all of them had an affect on me... I decided to completely pull the plug on vaping because I was tired of the panic attacks and .... it gave me... I still get very fatigued easily and my heart rate seems to get easily raised more quickly then it used to 4 months ago... also had shortness of breath for a while but that's recently gotten better and gone away... I may take a hit from time to time but if I do no matter the nic level or flavor my body always seem to have like some mini anxiety attack which is so silly in my opinion... and I really don't feel I can really draw in a HUGE deep breath I did some research and found that vaping at high nic levels for an extended period of time can destroy ur lung tissue in ur lungs... I don't know what to do cuz of the weird chest pains... I do have VERY bad anxiety and found that u can have weird chest pains with anxiety... I crave vaping all the time but every time I I almost have to pay I price for hitting a vape... could someone please give me some guidance... can I still vape? Am I allergic? Should I see a doctor? Or is it all in my head? Any input helps thanks
