I have been on Phentratrim (because I take blood pressure medicine) since October and have steadily lost weight. My friend did the enhancer for 3 months and then was convinced to switch to the All Day to speed up her weight loss. The All Day made her jittery. She tried to finish the All Day but ended up going back to her enhancer.
Our consultants have told us that the All Day is the strongest, then the enhancer, then phentratrim.
I would just see if the switch makes a difference in you weight loss. If there is no difference, then figure out which one (Phentratrim or All Day) you like better (or cheaper!)
