I will try to keep this short and sweet. My name is Derek, I'm 29, average weight and hight. I use a SMOK AL85 stock unit. Usually vape 12mg to 18mg nicotine using pg,vg,50/50(no difference in symptoms other than pg tend to burn my throat. I want share my experiences from the last 5 years of vaping and hopefully help others who may experience what I have been going through. For about 2 years now I've had issues with my health due to chain vaping 1.2%-1.8% juice. It took me 2 years now to realize my problems were from over using nicotine. I've lost $1k-2k in trying to get to the root of my issue. Symptoms= Shortness of breath, tight chest, random heart skips and quick heart pains less than one second(1-3 a day), tight throat, lump in throat feeling when laying down. When driving symptoms increase(mix of chaining, anxiety from symptoms, and posture), bloating, acid reflux, relentless energy deprivation, dizziness, feeling of fainting, slight visual colors and light usually accompanied by the dizziness. And 3 kidney stones along with rapid tooth decay, bad breath, trapped air in stomach, all from dehydration due to chaining a vape. My diet and activity level before my realization of my own self abuse from nicotine was quite poor and exasperated these symptoms. Unfortunately the vast amount of problems fit my diagnosis into too many categories and caused me to lose hope which also made it hard to cope with these issues. Since I started a perception to Adderal about a month ago, I have been able to curb my bad self discipline and have cut way down on the nicotine which slowly over a couple of weeks has removed almost every symptom except from dehydration, but that's because my medication makes this worse. I now drink 5-6 bottles of water a day and I feel like I have my control back over my life. The instant dopamine you get from vaping nicotine makes it very easy to abuse without even thinking about it. It sounds so obvious what my problems were from, but once your dragged that far down, nicotine is the only thing that makes you feel better. Just be careful guys and gals, don't make the mistake I made and abuse vaping at extreme levels. I will always stand behind vaping for people trying to quit smoking and for people that self medicate with nicotine(stress/anxiety). Oh and drink water, and then drink more, and a little more lol. My liquid intake during this experience consisted of soda, juice and energy drinks. I should add, I have pretty bad depression on top of the ADD, just caused by hormonal imbalances, also possibly due from diet and lack of exercise. I have since walked a different path I live and feel almost 100% again. Love ya all, pce!
