Hi all. I just purchased a 2nd hand (new condition) Alpha Stim SCS. See here: (commercial URL removed by moderator) I have read alot of different info online in different areas about it. It has said to help CFS and Fibro by improving neurotransmitter function and helping the nervous system. I used it last night for the first time, but on an extremely low setting (half way between 0 and 1, and there is 0-5 on the dial). I didn't feel anything big from it yet, but today I am very brain tired (am most days anyway though), but a little more today. Im not sure if it was the machine, or if i just took a little too much melatonin (which happens easily for me). I might take today off, then try the machine again tommorrow. Did anyone who used it get an initial tired type of reaction? Or know if this goes away with continued use?
