Need Help!!!

I have been taking phentermine 37.5 for almost 4 weeks. Since I began taking them, I have lost my cravings for sugar and carbs. It has really curbed my appetite. I am counting my calories and I am trying to exercise several times a week. I want to make this a lifestyle change, with the help of the medication to get me kickstarted and going in the right direction. This drug totally pulled me out of my deep depression I had sustained through the winter (to the point of only wanting to stay in bed, even while on vacation in Key West with friends). I am really focusing on eating good things, but I do not think I am eating enough. Since beginning the pills, I have only lost 6 lbs. I figured the pounds would just come off. I have tons more energy now and motivation, and feel GREAT!!! But I just feel like I should have lost more by now. I had hoped for 10 lbs the first month. My clothes do fit better, so I know I am losing some inches...

Last summer, I had a similar experience. I logged my calories everyday on here, along with my exercise. For me, working out makes me NOT hungry. In three months time last summer, I only lost 10 lbs, working my butt off and eating super healthy, but possibly not netting enough calories.

All in all, I'd like to lose 35 pounds total, to put me in my healthy weight range (I am 5'5"...rounded up) and at a healthy BMI.

My diary is open, so please advise KINDLY. I do not want to drink protein shakes for the rest of my life. I want to eat normal foods both at home and when I go out. I want to be healthy and feel good about myself. Like I said, this is a lifestyle change for me...

Someone please tell me what I am doing wrong,
