Well I have didrex, but im prolly not gonna be much help because I havent been taking them. LOL Because of the Holidays and all I havent taken phen or didrex that often. Didnt want to waste them. LOL But I have taken them, and they do give me more energy then the phen. I still get hunger pangs while on didrex (and phen), but they go away pretty quickly(with didrex). And they do also help me to feel full. I was hoping for the jittery effect. Something to make me feel as though I just cant sit down, and didrex didnt do that, but as I said It did boost the energy more than phen. When I do take them I take didrex one day and phen the next so I cant say which works better as far a weight loss is concerned.
I cant believe you found a site where they are cheaper than phen. I searched for days and days and never have I found them to be cheaper. Send me the site in a PM if you dont mind.
Sorry I wasnt more help.
