There is no specific advice I can give you that can help you with your current plight, other than to keep playing in these loose games since these are some of the most profitable games to play in and always play your best and never go on tilt.

I will give you some references though to help guide you in these loose games.

1) "Holdem Poker for advance players", by David Sklansky and Mason Malmuth, pages 152-181.
2) "Getting the Best of it" by David Sklansky, pages 75-86
3) "Small Stakes Holdem" by Ed Miller,David Sklansky,and Mason Malmuth, all pages.

Good luck in the future.
