"i started phentermine on 10/11/14, start weight was 249. as of today 10/14/14 i am at 241. that&#039;s 8 pounds that i lost in 4 days! i did change my eating habits to low fat and have walked 3 miles every day. also, i have been drinking only water. i cut out my diet coke that i was addicted to.(if i can do it, anyone can do it!). i feel great with no side effects. i truly believe in this medicine. the only thing you have to remember is that it is a lifestyle change. i wish everyone the best."
