agreed mimi. its very easy to vape too often..its very addictive, hehe. my thought was to have low lvl stuff for sitting around the house, and higher for when i was at work, and could only sneak a few puffs every once in a while. i'm doing better now, but unfortunately, the symptoms of underdosing and overdosing are too damn similar.both give me light headed dizziness and heart racing-i'm very familiar with underdosing since i would have to go 4 hour blocks at work when i was on analogs(no smoking on the premises, and not allowed to leave the building except lunch break)...i started using a touch of chewing tobacco to offset that.now i sneak into the bathroom every hour or 2 to vape.
