Spinoi I had this problem a few weeks ago and busted through my entire bankroll. This is what I did.

Just like everyone else said, just start playing straight up poker. When you make a hand, bet it. Don't check your made trips or set and try to be tricky/trappy, because that is what makes decisions hard (When the op doesn't know what you have).

If you just make a hand, and just bet it hard, like they said, over-bet pots the whole way.

If they don't call fine, but at least they didn't suck out on you. You will be suprised at the idiots at 25NL and 50NL that will chase you the whole way with second pair, even though you have been a repping a huge hand the whole way. It's almost like they expect you to be trick/trappy.

Playing straight up poker again works at these levels and it's what got me back on track.

Hope it helps.
