Started pill June 24, it's June 27 and the scale hasn't moved which is fine. Hoping by day 7 or 8 I will see the scale move atleast a pound.I'm 5'3'' 165 lbs. looking to get to at least 130 lbs. how long before you start seeing results? This is my first time taking phentermine. First few days was really rough, made me feel nauseous and sweaty almost like I'd pass out. Had slight headache and couldn't sleep also had tummy cramps and diarrhea on 2nd night. But today (day 4) I've felt a lot better. Also the doctor gave me a fluid pill to take with the phentermine and said I'd lose weight quicker? Anyone else take fluid pill with the phentermine?
