Hi - I've been googling around and can't seem to get good info on this and am looking for a little insight. I started vaping 4 days ago. I've been a half pack or so smoker for 20 years and keep falling on and off the wagon. I smoked menthol lights so got the 8MG nicotine liquid in a menthol flavor. I have probably taken 20 or so hits a day off the ecig for the last 4 days but it seems to be making my sinuses and tongue burn and my lungs ache ... like even worse than cigarettes! I suppose it's possible I'm allergic, tho I don't have any other allergies at all. If so, I'm bumming cause I really think ecigs could work for me and get me off cigarettes for good. Any ideas? thank you!
