I have been on Phentermine 37.5 on and off for about 5 years. My doc recently added in 25mg of Topamax. I haven’t started the topamax yet but had a question maybe someone could help me with. I am a nursing student in my 30s and graduate in 4 months. My concern is the memory fog and spaced out feeling comments I’ve read. How bad is this and how long did it last? I put on 30 pounds QUICK with nursing school and have taken 20 off in 2 months with the Phentermine alone. It’s 25 mg of topamax... what do you guys think? I have spring break coming up so I thought about trying it out then. Is the memory thing awful? Or does it get better? Thanks!!
