"started taking phentermine 37.5 on 3-6-17 weighing 274 lbs i&#039;m 5&#039;3- 40 yrs old. as of today 3-10-17 i weighed 266 lbs. it definitely kills the appetite and keeps you energized. for the past few days i have had severe nausea coming &amp; going. due to the results i am seeing i most push through. i have had no success in the past with all of the &quot;other&quot; dieting solutions. i&#039;m currently taking 1/2 a pill a day in stead of the - 1 tab a day. trying to see if it will calm the nausea.  looking forward to keeping you all updated. best of luck!"
