I had a very similar experience except I was a student at the time. I had no job and therefore gradually my sober life became less and less. I'd stay up later into the night, wake up later, and light up earlier. Eventually I got to the point where I was high all the time, but not happy. I had to move house and ran out of weed so I just decided not to get any more. The next couple of weeks were weird. I couldn't sleep properly. But things got better. I've smoked a couple of times since but have no desire to do it again now even though I know it does feel good.
