I just started Phentermine37.5 Phentermine last Wednesday and noticed I started to get headaches and feel sleepy around mid-afternoon. Any ideas what to do? I've read to drink water and I do but how much?
try a piece of candy or two, sometimes it can be from a sudden drop in your blood sugar levels that you are not use to. that happened to about a year ago and i started carrying hard candy with me all the time. and it helped alot.
