I bought phenterfein on ebay and I have been on it for about 3 weeks now.  I started taking 4 caplets a day.  When I wasn't seeing any results, or feeling anything, I slowly increased to 6/day.  I had read that if you take the maximum dose that you would be bouncing off the walls.  I also read that I should be losing weight.  Well, much to my disappointment, I have not lost any weight.  I also don't feel jittery or like I am bouncing off the walls, so I don't know if I got a bad bottle or what.  I was so excited to get the pills and I felt like something might actually work for me.  But, alas, no such luck.  I wanted to write this review because I have been reading tons of reviews of products to try to find one that works for me.  I have read only positive reviews of phenterfein, so that is why I am shocked that it isn't working for me.  I am going to finish my bottle, but unless something starts happening soon I will not buy it again.  I wish I could find some pill that would help me lose the weight.
