I hear ya, LIP. I could go without weed for days, weeks, even months if I so desired to. I used to, actually. Now it's an issue of pain control for my Fibromyalgia and Irritable Bowel. I feel sick, nauseous, and highly sensitive to pain/pressure/temp if I don't smoke at least once per day.

I am dependent on weed for pain control, not to get high. I rarely gets stoned/high anymore, anyway. It is nice to take a break once in a while though, if my pain level is unusually low. That's the difference between medical and non medical users- we can stop, but it's much different for us because of a legitimate reason.
