You need to be careful. The feeling of the 'High' isn't going to get any better than it is now. What happened to me, and a lot of other people, is that the high feeling becomes 'feeling good' and not high becomes 'not feeling good'. Gradually it progresses to being high = feeling normal, and not being high=super grumpy.
Pay attention to your moods and your use patterns. If you can't say 'No' now, lets figure out a way to make that happen.
