It is so good to read that giving the stim a full try over time is beginning to show some positive benefit for you, Lily!!

I found that using it continuously although varying the intesity of the signal allowed my body to "soothe" into the signal overall as a pain management tool, while giving me rest, at night, then more vigorous stim, during the day when I needed it. This kind of 24/7 technique for me is working to help me just bodily acknowledge "it's there" and use it for the intended purpose.
Hoping and praying that the rest of your efforts at Trial go well,
