I think I need a little of this today — I am taking Sudafed for my sinuses and my ability to focus is zero, zilch, nada.
You can get a free sample of Focus Factor from Sam’s Club. It does require a Sam’s Club membership.
There was also a Bayer Sample, but unless I am crazy, I couldn’t seem to figure out where you put your information. Again, Sudafed makes me a little weird, so if you find it, let us know.
