There is something fucked up with my body. I've grown a tolerance and I can't get rid of it.

I smoked a half ounce in a month (that's a lot for me) and I took a 1 week break. Yesterday (day 8) I smoked 2 bowls and had the usual "tolerance" high, which makes me really tired only.

No smoke for 1 week and I still have the tolerance.
