What happend to all the good focus formulas? Does anyone remember clear edge back in the day that nutra was selling at 10 bucks a bottle? This stuff was great. Kept you alert without the caffeine,crash or making you jittery. Looking around alot of these blends are discontinued or if one is available it contains caffeine. I'm trying to find a good one to keep me awake cause I'm getting sensitive to stimulants again. Any suggestions?
