At the limits you're playing at slowplaying is the death. People check through like a baggage claim and chase draws about half the time.

Flushes/straights are about 1/3 to beat you on a draw. Bet the pot = make money always. Slow play = make money 2/3 of the time.

Here's a short list I made when I was on a losing streak early in my learning career:

1) Bet the pot. Bad beats happen and you will always profit over losses if you be the pot.
2) Fold middle pairs
3) Stop bluffing unless you know you're profiting from it.
4) Lay off the implied odds
5) Lay off the draws
6) Fold to re-raises preflop if your hand is weak (Group 2 and above call them down, reraise/push all in with monsters like QQ, KK, AK/AKs, and of course AA)
7) The blinds are cheap. Wait for a dominating hand as opposed to just a good hand.
8) Trips get slowplayed alot. Take advantage of this on your draws.

You might also want to play in some cheap SNGs. You get to play so many more hands for your dollar, the experience is amazing, and you learn that risking your stack on coinflips and marginal pots is a losing proposition.
