Just started vaping Nov 1,2014. I was very sick last week. Had flu like symptoms. I already had a physical for Friday. I told my doc about quitting smoking reg cigs, a 42 year habit. I have GERD and he saîd a common complaint with the ejuice is indigestion and so he doubled my stomach meds. Still feeling a little sick, but a little better today. I will let you know when this goes away. Still going to try and not go back to the regular cigs. Wish me luck ! Thanks
