I've been vaping since January of this year but the last 5-6 weeks I've been on my backside with aches and pains, headaches and major flu like symptoms. I've been to the Doctor who did blood tests etc etc and all came back clear. I told him that I'd given up smoking and congratulated me on my giving up, he asked me how I'd given up? I said "I've been on the Vapour Tanks", the reply was "hmmmmm, that explains your flu like symptoms". He asked me if I'd got any of the juice on me? I said "I've got some in the car". He asked me to go and fetch it so he could have a look. When I went back into his room he looked at the bottle and again the reply was "hmmmmmm" his worlds were, "it seems like your allergic to some of the ingredients like Glycerin". I asked him if that could be the cause of me feeling ill all the time? He said "yes some people are OK with it and some people aren't, you aren't OK with it. He advised me to stop using the Vapour tank as he said that the liquid could be the main cause of me feeling ill and that there was no regulation as to where the liquid comes from or how it's made for example China and other countries. I stopped using it that day and within hours I'd started to feel better, the next day there were no aches or pains nothing. Last week I thought I'll give my Vapour tank a whirl and see what I'm like, I went and got some UK made juice with a 70VG/30PG mix, within minutes of using it I'd got a stinking headache, and within an hour I was on my backside again with flu like symptoms aching all over, I loaded up with Ibuprofen and off to bed I went feeling like I'd been run over by a Train. Anyone else having any problems, I'm back on the ciggies and want to kick them into touch.
