Hello Christy , I take phentermine too. I get up and first thing I do in the morning is drink a bottled water and I eat breakfast . I eat a healthy breakfast like oatmeal and some fruit in the morning. I take my phentermine within two hours after that. I drink water a lot during the day but also try to eat small things throughout like fruit, boiled eggs , nuts , a healthy lunch , water water water, I may eat a small dinner by time I get home even though I'm not really hungry. But you must learn to eat right on these pills and not allow your body to starve because at some point you have to come off them.
