You're becoming mentally "addicted". If you care enough it should be relatively easy to quit for about a month. You don't have to give it up completely, but it would be wise to cut back before you smoke yourself retarded and wind up in section 8 housing.

There's no physical addiction to marijuana, it's all mental. You LOVE getting high so your mind tells you to get high, but if you quit for a while you won't get any major drawbacks, you may feel lightheaded, tired, or agitated for the first few days, but it's no big deal. Just get drunk or something.
