After 2 days of switching to no nicotine and glycerin...

[ruandisheng]

I have been vaping for a while and after school in front of my computer doing homework, I find that I vape continuously with the passthrough. Because too much nicotine I find it really hard to sleep at night. So I switched just usp grad glycerin mixed with water and menthol crystals.

The results were me coughing out some brown phlegm and weirdly breathing better... Anyone else have tried this?

i was off nic for over a year--just went back to using a little in the morning.
I tried menthol crystals but they did bad bad things to me.
I have never coughed up anything---of course my lungs were clear my last x-ray before I made the switch.

menthol from what i was told was used to help soothe your throat and lungs when you have a cold, somehow you think your breathing better from the cooling sensation? or maybe it really is helping

Sounds like you may have used too much menthol. How much did you use?
