Chastity and orgasm denial discussion

I managed to get a solid night’s rest for the first time last night, waking up just once because of nocturnal erections. I’ve been wearing my CB-6000S device for almost a week now. This morning, while flaccid, I noticed there’s room for about three fingers between the ring and my scrotum. Everyone says this is the moment to downsize the ring, but should I hold off until my sleep patterns improve? The ball burn persists, though lubricant helps manage it effectively. If I switch to a smaller ring size, how do you handle the spacers? I recall reading that using a larger one might be better. Right now, I’m on what I believe is the middle-size ring paired with the smallest spacer.

Thanks
