"so i&#039;ve recently started taking phentermine 37.5mg  on 4/13/15 and today makes my 3rd day and so far i&#039;m loving it!! it gives me the energy i need to start my day without having drink coffee which has so much calories! i weighed myself on monday i was at 186 and now i&#039;m 183. i love how i don&#039;t have an appetite for food or if i do eat i just take a few bites and i&#039;m full. i haven&#039;t experienced any of the side effects except just a slight headache which is normal to me."
