Hi, 23year old female,5'6,and 209lbs. It is my 3rd day on phentermine 37.5. Yesterday I weighed myself just to see if anything had changed and I had gained 2lbs! I don't have any side effects except for a dry mouth. I have been drinking tons and tons of water. I only feel a slight boost in energy but its bearly noticeable and I feel like my appitite has not gone away just yet. I don't experience any hunger pains or crave anything but I still think about food. I'm not sure if that's normal? Every other review I've read says no one wants to eat and I still kinda do. I know I'm only 3days in but I am really counting on this to work for me and am starting to get worried it won't. Any advice??
