So vaping (24mg high) all day yesterday and drinking a fair amount so I'm not paying too much attention to how much I'm taking in. This morning: Massive headache, shortness of breath, laboured breathing and a heart rate of 110-115 bpm. Vaped away all day in the emerg (on LOW strength)while waiting for test results (security checked me out than laughed about, they'd heard of e-cigs) (chest x-ray, blood work, ecg, etc). Final verdict: in fine heath, nicotine poisoning, take some valium, and slow down on the vaping!
On a side note if you've vaping away on a nice flavour and you take a shot of vodka it give the vodka the flavour - though drinking a lot straight vodka and vaping is gonna give you a super nasty raw throat.
