Where's my game?

I'd really like to be writing some insightfuly post about how I improved my game and played an awesome match tonight. Instead, I'm wondering why I've lost every single match I've played for the last 3 weeks (geez has it really been 3 weeks? yes, yes it has), with the exception of one doubles match we won.

First I need to make i clear that I'm a 3.0, been playing a lot for about 6 months now, but I consider myself solid 3.0. Ok, so I played a 3.5 two weeks ago and he beat me. That's fine, a 3.5 should beat me (6-2, 6-0). The other matches have been outside of www.TennisPulse.org and so they aren't listed there, but the scores are similarly bad. I've been playing other players that I'd consider equal to me, not better, yet the same pattern seems to repeat. The first 4 games are usually tight 2-2, and then I go to sleep. Maybe I'm just out of shape and get exhausted after 4 games.

Tonight I was just so freaking lethargic I didn't even come alive until I was down 6-2, 5-0, and I then played one really strong game,and then collapsed in exhaustion for a final 6-2, 6-1.

I hope things turn around soon.
