Phentermine
"I started phentermine 5 days ago. Today is Monday September 28 2015. I haven't lost anything.  My weight is exactly the same as when I was weighed in the clinic. I've seen a ton of people who have lost weight in their first week but I don't seem to be one of those people. This is a little stressful because I'm nearly 100 lbs over weight. I'm not a big eater already so maybe this drug is for people who over eat? I also heard it speeds your metabolism and that too causes you to lose weight.  Maybe it's still too soon to decide if this pill is work in or not but hopefully it starts to work soon. I also work out daily for an hour. Sometimes more. Ughhhh!"
