Last night I turned my stimulator up from a 2 to a 4 and I do believe it’s kept me sane. Earlier I moved it back up to a 6 which was originally where I had it before I had to dial it down due to over stimulation. I sometimes won’t know until 24-72 hours later whether it’s going to over stimulate my body. If it does I will feel strong vibrations in my legs, nausea and usually it hikes my heart rate. No matter what I’m thankful to have this device that for me only helps around 25 percent, but that 25 percent is huge when you’re hanging by a thread otherwise. Not a cure, but a tool to help take the edge off my nerve pain!
