The dry mouth thing does go away, in my case at least. I have dry mouth problems that will never to away because I take 1500mg lithium each day plus couple other meds. About 2 weeks after I started vaping my tongue turned white, felt like someone put superglue over my taste buds, and it went numb. I dealt with that for a couple weeks and then it went away. Now I have no more problems with dry mouth than before.
Once I ran out of supplies and smoked a couple packs of cigarettes, made me dizzy and sick, don't underestimate the contents of cigarettes above and beyond nicotine. No more tar and heavy metals now
Those complaining about upkeep on attys, switch to cartomizers with a tank and throw the $2 things away when they die. I stuck with ego-t system way too long, it was a big pain in the neck. Great idea in theory, horrible in execution.
Ordering online is a pain, especially considering sometimes things arrive in 3 days and sometimes it takes a month. Wish Amazon handled vaping supplies other than PG/VG, I get stuff from there almost immediately.
Bad juice is a problem, I bought a huge bottle of vanilla that was so strong, I had to equip myself to make my own juice just to dilute it. Glad I did now, I can make it how I like it. Always seemed like the flavor was so weak that it just managed to taste a little worse than nothing or so strong I couldn't vape it without gasping.
I try to tell people that vaping is cheaper than smoking, well that's good in theory but I've spent more on vaping over the last few months than I would have smoking. The juice is cheaper but because of all the hardware I've bought it has become quite expensive. I should be stocked up now so I shouldn't have to buy much for quite awhile. Sure, lol
