No I doubt it. What is the PG/VG of your juice and what nicotine level?
VG can give me gas/heartburn type of indigestion.
Typical too much nic symptoms are headache. blood pressure changes, rapid or irregular heartbeat, overall yucky or hazy feeling. Skin/mouth/throat/lungs can get irritated (nicotine is a skin irritant) especially if you are
vaping 100% PG which is also what the prefilled carts often are. I guess if you are vaping constantly or not used to nicotine then you could get sicker.
Forgetting to drink fluids can cause dehydration
And just stopping smoking can cause some symptoms for a few days (cigs have another 4000 chemicals in them)
Accidentally swallowing vapor can cause gas or heartburn too. Sometimes those food flavors trick your mouth and trigger a swallow.
Do you have a different juice to try? Sometimes a juice maker makes a mistake and a juice may have to much nicotine or be sloppily made. Stick to reliable brands. A
