sweating

I've been vaping on and off for over a year, still smoking a few ciggs a day...and 4-5 mornings throughout this time period, about 30-40 mins after I wake up, I get horribly ill...vomiting, covered in sweat but freezing with a slight headache. The first time or 2 it happened, I didn't even think...

I've got a few plastic juice bottles that are sweating juice. What the heck is going on with that? I can easily transfer to glass, but what's with the sweating...from the bottom it appears.
