Started taking this to lose weight along with cycling I do about 150 miles a week.  Been on it for about a month and lost about 10 lbs.  Decided tonight to stop taking it due to stomach pains and at times feeling nauseated,,just don't like the feeling it causes my stomach.  In the beginning I felt I had more energy but lately now feel tired more and catch myself wanting to take a nap.  I was taking 2 tablets in the morning and 2 in the evening about 30 minutes before meals.  Definitely made me urinate more as well.  I am done with this, but will continue exercising and controlling my food intake
