I've been taking Slimquick for a couple weeks now - since I was laid off I've gained almost 20lbs - and it has killed my motivation. It has helped with the energy level quite a bit. Only issue is that I pee A LOT and I have a hard time falling asleep some nights. I'm a boredom eater, and it has helped.
A bottle of 75 pills was $20 and for taking two a day (supposed to take 2 a day for the first week, then 4 a day, but 2 is working fine) the price isn't too bad. I wasn't up for using something like Xenedrine - and I always got sick off the acai drinks I tried while I was working (store sold them)
