Query: Trimspa Ultra Works!

I tried Trimspa after trying unsuccessfully to lose 10 pounds on my own, I would eat right for a few days, then pig out for a few days. I had only coffee in the morning then took one pill at 12:00. It completely curbed my appettite. I ate one small bowl of cereal at 5:30 pm and that was it all day. I never took another pill because I never felt hungry. The next day I took one pill at 10:00 and ate one small meal all day. Same thing the next day. The very first day I did get a bad headache after taking the pill. The next day was better and the 3rd day I didn't get one at all. I gave a few pills to my sister-in-law and she tried just one pill yesterday. She called me this morning and said, "Girl, you are on to something". She has no side effects at all but the pill killed her appetite! I have tried many supplements and nothing has worked for me since they banned ephedra. This stuff is great! It is worth a try!
