If the problem is that the stimulation itself is irritating you, the thing that works for most people is to reduce the intensity. Most people do not realize this, but most of the time, less is more with ICES-PEMF.
Keep in mind that ICES-PEMF is about 500X more inductively efficient than most other PEMF products**, so it takes very little energy to get good effects.
Just as an experiment, try this:
Just keep reducing the power until it does not interfere with your sleep. Then, stick with that intensity level for a while.
I did exactly this a month ago for my left hip/CRPS, and I am very happy to report that by reducing the intensity I had no interference with my sleep, and much better results on my left hip pain, which now, is almost entirely gone (yay!) after using it this way every night for about a month.
** I am not exaggerating, it is really about 500x more inductively efficient than typical PEMF products. I can show you the math.
