obesity
"I have been on phentermine for 3 days.  I have increased energy and a mild case of dry mouth. I do feel "spacey" at times, but not so much that I cannot drive or work. I am working out harder and drink more water.  I no longer feel hungry and I have control over my sugar addiction.  It took me 3 weeks to lose 12 pounds before I started phentermine.  I have lost 5 pounds in the past 3 days.  Tonight is the first night I have not exercised, while on this medication.  It is 1:15 AM and I cannot sleep.  Will I stop taking this drug?  NO!  I will be sure to exercise every night, to aide with sleep."
