Id say excercise is my biggest pain in the butt, Ive tried every eating plan under the sun until I found WW's about 2 months ago.. seems like the first week is always the hardest especially when coming to grips on portion sizes.
Now thankfully its better and I get full faster! Hang in there though and drink lots of water, I notice I dont lose as much when I slack in drinking it... supposed to drink half your weight in water a day, some days I feel like Im swimming LOL but it works!
Good luck on your WW's journey!
