I wrestle around with my kids (3 and 5) and play Wii Fit with them. That's about it. I have been a little depressed the last couple months when the kids are around (I only have them 50% of the time) so I don't eat much. I think the not eating is probably the biggest reason for my recent weight loss. That and the fact that I haven't smoked weed as much this semester which is the biggest cause for my late night snacking.
I'm not depressed all the time, it's just a recent rough patch and I know I'll be fine in the future.
