I ordered Phenterfein through an ebay seller.  I used to take Phentermine (which maintained my weight at 123 lbs for about 5 years).  I wanted to try Phenterfein to see if it worked better.  I started to take the pills Dec. 20, 2006 and it's Jan. 3rd and so far I noticed an INCREASE in appetite (cravings for tomatoes, pizza) that kind of thing.  It did cause diarrhea....is that what it's supposed to do????  I didn't feel any energy rushes (still sluggish).  I will give it a chance and report back in about 2 weeks.  I don't see ANY weight loss.  If you plan to order this product, email me first, and I will be honest if it works or not.  I have taken phenfen when it first came out and that worked so well.  I was hoping this product was like phenfen.
