Yes, I tried those pills, and many others, and NO, none of them worked, because I refused to admit that the ONLY healthy way to lose weight was the good old fashioned way of, Cut calories, increase exercise. I joined Jillian Michael's website for $14 a month. Jilliam (JM) e-mailed me exercises I could do in my own home with only an exercise ball and hand weights. She also has a diet plan, but I found it too difficult to follow while working and raising a family. I followed the caloric intake she suggested, and I lost 20 pounds in 5.5 months. It was a long process, but 2 years later, I am still down 18 pounds! What most people learn is that if the weight comes off quickly, it will return quickly.
If you can get yourself in a habit of drinking half your body weight in ounces of water EVERY day, you WILL begin to lose weight. At first you are in the bathroom all the time, but your body adjusts, and the weight begins to fall off. Set a goal of 2-3 pounds per week, get friends or buddies to help support your goals, and you WILL achieve your goal. There will be good days and bad, but your buddies will be there to pick you up, celebrate your successes, and kick you to move on toward your goal. You CAN do it.
Good luck!
