stress!

i have been very stressed this week. and it showed on the scale. i gained 3 pounds out of those three pounds 2 pounds was body fat mass. and 1 pound of water. damn. i need to try to relax so i don't screw myself again. im working out like crazy. 1 hr 30 minutes day a and 1 hr day b. and following diet plan made by dr. so the only thing i can think of to blame is the stress.
