On and Off again and again

Actually, I started trying to lose weight in Febuary. So far with the help of phenermine and my doctor I've managed to lose 32 pounds. The problem is I can't seem to stay on target.
  I really wish I could get through this blah spell and get motivated and stay on track.I'll do good for 2 or 3 days then for 2 or 3 days I just go crazy and eat everything in sight and at night, oh boy, See I worked night shift for 25 yeard and am now a stay at home mom of 2 teenage girls so I even wake up hungry at 2 or 3 am nearly every night.
 Tomarrow's another day.I'll try again.
