Anyone else ever been sick whilst vaping? Never actually vomited but have had to dangle my head over the toilet whilst gagging and spitting 3 times now, and felt rough for about 30mins to an hour. It's always been in the morning when i've had an empty stomach and always been on that 'nicohit' stuff that is so prevalent on ebay, feels like ive been huffing on an air freshener and have something inedible on the back of my throat...either that or i've over dosed on the nicotine maybe?
