I have different 'modes':

I can smoke multiple bowls a day and fall asleep without smoking right before bed. Just tire myself out.

I can smoke a single bowl before I go to bed and go right to sleep. By 'right before bed', I mean within 30-45 mins if hitting the pillow.

Now...If I say smoke like 2 or 3 bowls in a day, I'll have to smoke right before I go to sleep otherwise I end up staying all night. To smoke multiple bowls and just fall asleep...it takes likes 5 or 6 bowls in a day. It also depends on the quality of herb.
