Phentermine / topiramate
"I've just started on the 7.5 XR 7 days ago after 2 weeks of the trial dosage. Thankfully no side effects but also no weight loss at all. I feel as though I'm eating less and not quite as hungry as usual and I have started walking 2 1/2-3 miles 6 days a week so I'm really puzzled why no weight loss. 
I am hoping I'm just off to a slow start and will keep doing what I'm doing and try to cut out my carbs a little better. 

I will update at the end of my month but any thoughts or suggestions will be welcomed!"
