Sounds to me like you should be playing more MTT's with entries of up to around $50 (2% of your bankroll). If you want to play cash games and you think that your up to it, you should be aiming for $5/$10 fixed limit or $2/$4 NLHE. You should average around $20 to $25 an hour profit (depending on the site), if not you need to be stepping down until you are winning. Personally, I think its wonderfull to see people step up to your level of play and hand you their money, so be careful.
I would put some of it aside to learn a new variant of the game for fun - it helps during those dark days of poker.
