Well I started on the Phentermine30mg about 2 months ago. And up until now I've been getting great results. I've lost 30 pounds so far but i still have way more to go. These last couple of weeks i've noticed that it hasn't been working that well anymore. I haven't been thirsty AT ALL..and I've been wanting to eat alot more. The only thing that's the same is my sleeping problem!!! I have a hard time falling asleep at night. It seems like i wake up every hour and look at the clock!! I haven't lost any more weight at all...it's been the same for 2 weeks already. I'm thinking about asking my doc about a higher dose. Does anyone have any suggestions???:helpsmilie:
