Today I have a crazy issue. I clean up my AVS and atty and then fill. The atty tastes crazy burnt and when I try to get through it a few puffs...I decided to change to a new atty. I opened the AVS and my liquid was almost all gone! Not much in the bottom chamber. I changed the atty and filled. Same results. What is going on? It seems like my GGTS is burning up the liquid...could it be the spring? I tried pulling it out a bit on the bottom cap, but that didn't help. Anyone else have any ideas? I've gone through 2 AVS full fills in 20 mins.
