OK well, since January of this year, I've lost a lot of weight (like 80 lbs), but now I find that I'm tired during my workouts and can't go nearly as hard as I used to on some days. I've also found that I get really hungry in the middle of the night, and usually crave carbs. I've actually gotten up and cooked pasta once or twice. I was losing 12-15lbs a month, but now it's more like 5-6, which I'm assuming is because of these really bad cravings. My diet was given to me by my PT, but as I'm no longer with him, I can't ask him this, and it is a healthy diet where i'm getting everything I need. Also, for the record, I am female and Type I Diabetic. Also, I still have about 50 more pounds until I get to my final goal.
