Lessee, new vaper tricks...
The first kit I got was one of those cheapie crap minis, the automatic draw type that you pick up at the local cigarette store because it a) looks like a cigarette and b) they sell the preloaded cartridges. So I tried valiantly, having read that you could buy juice and refill things, to refill those cartridges. I'm pleased to say that it worked about 75% of the time. (The other 25% of the time, I'd get a mouthful of juice. Ew.)
I forgot to wash my hands after reloading my eGo-T tank. Went about my business, then yawned and rubbed my eyes, as it was getting late at night. OW. Never get juice in your eyes. If and when you DO get juice in your eyes, I strongly advise AGAINST using one of the eyedrops (like Visine) that has PG in it, because that doesn't help as you already PUT PG in your eyes (along with all that nicotine). This was something I was unaware of. Hey, who reads Visine bottles, other than to assume it'll make the burning-eyes better? Should this ever occur to you (although it won't, as you're far more intelligent than I am and always wash your hands after filling tanks and getting juice on your fingers), get an actual eyewash, like a Bausch & Lomb-type eyewash that's JUST mild saline solution, and rinse thoroughly. It helps for the couple of days of irritated-eyelids you'll have.
Not drinking enough causes you to sound like you just smoked a whole pack of cigarettes. No lie. Combine that with being exhausted (or having gotten juice in your eyes), so that your eyes are red, and have disheveled hair, and people start giving you odd looks as you're puffing on something which looks like a long cylinder. Yes, someone thought I was a strung-out drug addict smoking a crack pipe. They got over it.
Oh. And hamsters also do not like the smell of juice on fingers. They jump out of your hands and you then do a merry chase trying to catch the little beastie (with those juice-scented hands). Again, another promo for washing hands.
I'm much better now. Really.
