bad losing streak after BIG WIN

[bgd123]

so i win a $1200 on my first tourny then jump right into another one and win a little over $950...that was 4 weeks ago...i can't last longer than the first hour in tournys since then...i get sucked out on they will catch runner runner or they will go all in with 7-3 and catch a 3 on the river when i'm holding AK in every hand that has a decent size pot or if i go all-in...this happens for 3-4 weeks every time after a big tourny win....i go on TILT SO EASY and i'm fucking up the other 2 games i'm playing...i'll play 3 tournys at a time....

does this happen to any one else after a big win...do you go on a bad dry spell...this has been happening to me for the last 7 years....it's like i only get1 week a month where the cards will fall my way....
