I went through a stage like that last year...I could feel it really effecting me, in a bad way....I felt like shit, was doing the same shit everyday....I tried only smoking at night time....but got past the point where I needed it to sleep (due to getting into the habit of smoking before I went to bed) and got a point where the weed wouldn't get me stoned enough to get to sleep...so I didn't sleep either way.....so now I only smoke at weekends...
it sucks but I've got a month or 2 of college left and imo weed was effecting my performance at college...

But dude....I really don't know what you could do....sound's like you have quite a bit of weed all the time...the only thing I could suggest would be to quit...and just smoke on weekends....dunno dude.....tricky situation
