"i started phentermine 37.5 on 5-4-16 with a weight of 247 lbs and as of today 5-11-16 i&#039;m at 235 lbs. all i want is water! i have zero cravings for sweets or sodas. i keep my carbs at 100 a day. only side effects i have are increase in energy and dry mouth, which is why i always have a bottle of water in my hands."
