They helped me lose weight back when I got down to about 180 two years ago. Now all I can find is Stacker 3 XLPC, tried one pill and basically felt like I was having an anxiety attack and like my heart was going to come out of my chest. So needles to say that was a waste of my money. Stacker 2 never did this to me, but I cannot find it anywhere, so I was wondering if it's been discontinued? Can someone recommend something else? I don't depend on this stuff for my weight loss, only as a boost. I have a treadmill and total gym and a couple of other things that I don't know what they are but I use them. I wish I had the will power to diet as well because I would really like to drop 40 lbs by the first week of august. Not going to happen but I would at least like to drop 20.
