Phentermine
"I began taking Phentermine 37.5mg on Jan 28 2015.  In addition I am doing a low carb/low calorie diet of 1000-1200 calories a day.  I walk two miles a day and do approximately 1 hour of cardio a day.  My doctor prescribed it for 2 months on and one month off. I am currently two weeks into my "off" month of phen. As of today, April 10 2015, I have lost 40 lbs.  I find it to be an excellent appetite suppressant.   The only side effect I experienced was vivid dreaming the first week.  Cigna doesn't cover the prescription but with the GoodRx discount I purchase a months supply at Kroger for $11.96.  The doctor co-pay is $25."
