Hey chocolateluv,
Good to hear that Im not the only one whose weight fluctuates depending on when assessment is due! I'm super new here as well, and joined much for the same reasons.
I started exercising about three weeks ago (but had been dieting for a while before then, with only minimal effect) and I found that the combination has made be both stress less and feel that I can accomplish more. Sounds cliched, and I guess it is. Its also true.
Looking forward to seeing you around
