"i began taking phen on january 21, 2016. i have lost twenty pounds exactly and it has only been seven weeks. i feel amazing, and have virtually no side effects except the first three days my mouth was dry. the program i&#039;m doing requires me to see a nurse once a week, which is kind of a pain, but i&#039;m glad because they answer your questions, can increase or decrease your dose and obviously look at your progress. one thing to note: i am extremely active, and have an active job. i am shocked i have lost this much so quickly, and i hope they let me stay on a small dose after i lose my remaining ten to fifteen pounds so i don&#039;t blow up like a balloon right after my four months are done. i am really happy, i have never done a successful diet!!! :)"
