Ok right now I have a major problem with my game, and its discipline. Sometimes I just get in this incredibly spewy mode where I run huge bluffs, call down light, and most of the time tilt away BI's. Just wondering how some of you avoid doing this?? If I didn't do stupid shit like this I honestly think my win rate would be at least double what it is. Here is an example from tonight:

No-Limit Hold'em, $0.10 BB (6 handed)

Hero (CO) ($11)
Button ($16)
SB ($7.50)
BB ($10)
UTG ($22.20)
MP ($16.10)

Preflop: Hero is CO with A, 10
UTG calls $0.10, MP calls $0.10, Hero bets $0.50, 4 folds, MP calls $0.40

Flop: ($1.25) 7, 4, 6 (2 players)
MP checks, Hero bets $0.80, MP calls $0.80

Turn: ($2.85) 5 (2 players)
MP checks, Hero bets $2.50, MP calls $2.50

River: ($7.85) K (2 players)
MP checks, Hero bets $7.20 (All-In), MP calls $7.20

Total pot: $22.25

I have tons of examples like this and also where I make ridiculously stupid calls when I know I'm beat. Makes me want to throw up.

Advice?
