I was at zero nic for six months (have been vaping for two years no ciggies) went down to 3 for about a year before that,well I ran into a hot mess of stress , and needed some nic, so I picked up some 6 as opposed to somthing stronger,didnt want to od on it.since I have been vaping it I cant eat anything,not even bread without getting mad heartburn,this also gets worse when I vape it without eating.I have tried pepto to no avail, I have a shipment of 3mg coming in a couple of days,just to get me through until I can deal with what is going on, will that help? I have to have something to get me through and I havent had to take antacids for a long lon time is it the nic?I am really watching what I eat to avoid it....am I going to have to go back on antacids or what does anyone know about this? I would appreciate any feedback.btw I do not do caffeine at all if that helps
