I have taken them more than once, the first time it was in combination with another drug, and it was super effective, but after I lost what I wanted I quit. THe next time I tried them it was not as effective, I had more energy but was less active and did not drink water as often. The most recent time my daughter was 6 months old and I hated the way I looked and felt, I was up 4 sizes. I had to put myself on a schedule, take the meds first thing in the morning wait 20-30 minutes and then go walking for at least 30 minutes (we worked up to 45 mins). After about 8 weeks I was down to a manageable weight, I think it was about 15 pounds but the inches were incredible, like someone else stated ignore the numbers. My clothes fit, I felt lighter,and I could stand looking in the mirror.
The big thing is making a plan, and drinking water, oh yeah working out in the morning gives you energy the rest of the day, and the fat keeps burning!! Drink water and stick to it.
GOOD LUCK!
