I bot the Alpha Stim M new on EBay, 1/3 off but wtf expensive. Pain will do that. I've used it 1-2 times daily for two months with ear clips for FM pain, zero effect, very disappointing. Have messed with pulse rate and wave stuff a bit, just no effect for me. First time I got a bit tired and nauseous, probably should go high again on setting until that effect and back off. Will continue until my brain is fried since I bot it LOL. The little electrode stimuli do stop specific non fibro pain like my bicep tendinitis for two days. Will keep you posted. If anyone gets help from electronic hackin, let us know.
