OP - get some help. Smoking that volume isn't healthy. Seek some support group therapy and if that doesn't work some professional help. If you think you can control this stuff then try to stop for a week or month without smoking any.
As one addict to another (my weakness was gambling, not drugs) stop and get some help. You're running 90 straight towards a brick wall. Obviously you're addicted even to create such a thread. When I played professionally, I lived, ate and slept poker. Only time I wasn't at a table was when I was sleeping. I made damn good money but it cost me everything else. You're obsessed with pot and addicted. My short story is on here but seriously stop and get some help.
It's not to late to stop and turn around. Many people have shit that is larger then themselves. Some are lucky and never find that vice. Others aren't so lucky and stumble on some shit they just can't say no to. Get some help!
