I got the generic Adipex, Phentermine 37.5 mg manufactured by KVK Tech, The pills are small, white w/blue specks, oval pills with a k/25 on one side.I got tem at Costco. I have read on here that certain brands are better. Anyone taking these and have good results? I only started Sunday, but not what I was hoping for. Energy hasn't increased! Took a 3 hour nap at noon yesterday (took the pill around 9am). Today I wasn't as tired, but got that way around noon. My appetite hasn't been all that suppressed either. It's not as strong through out the day, but I am still getting hungry. Tonight, I'm starving. Ate dinner at 7 and was still hungry. Just ate an apple with peanut butter and I could still eat! WTH?!?! I am drinking a lot of water! Don't know what the the deal is! What does everyone else's pills look like and anyone taking this same pill and it didn't work? Thanks!
