After about a month of vaping I started to feel decidedly peaky but after 4 or 5 days everything settled down and it's been plain sailing ever since.
It might have been because I'd been shoving different stuff into my lungs than I had been for the previous couple of decades or, then again, I might have caught a bug - I'm not one of those people who says "I broke my leg while on a skiing holiday and it's definitely the fault of e-cigs" but it made me wonder.
At the time I blamed it on switching from those awful E Health things to a 'proper' Tornado with its 'proper' e-liquid as opposed to the mix of air, beige and gnat's spittle which had been in the E Health cartos. The again, I'm Irish.
Stick with it, Jacquie. We'll be waiting on the other side.
Metal stuff and batteries...
