I'm jumping on. Last winter I really packed on the pounds, fast (about 20 lbs - may not seem like a ton but I'm very petite). I got to where I couldn't wear any of my clothes but stretchy leggings
In January we made reservations for a July trip. In 5 months I lost about 18 pounds and worked out really hard and was in pretty good shape. I felt great on the trip, lots of energy and endurance. As soon as we got home I started putting it back on and now am up to almost where I started. My back and knees are hurting again and I get winded easily. Now we have a March trip planned and I know I've got to get back in shape or it's going to be hard on me, not to mention I don't want to buy bigger clothes...So I have 4 months. Every day I think I'm going to start fresh Monday - no drinking, cutting calories, going to the gym. I'll do ok during the day but then I don't have the energy to go to the gym and I go home and have a beer and eat too much for dinner. I hate the way I look and feel but I just can't get motivated enough to go full force. Hopefully this will help reading all your stories!
