I don't want to get too ahead of myself, there are several factors in play here...

I'm about to have a hormonal issue, the job situation isn't as bleak as it was last week, I have a lot of stressors under control this last few days, and there hasn't been any sort of death (knock on wood) in several days.

That being said, the financial situation is still total crap, thus affecting my ability to buy a pack of cigarettes. Day 3 of Vaping and I feel no depression symptoms. None.

Might there be something to the Co2 theory?

I'm not looking a gift horse in the mouth or discounting the other things... But the timing is interesting.
