Patch not staying put

So I’ve been in HRT now for approx 6 months after 2/12 years of hell, I actually thought I was loosing my mind until a friend suggested I might be peri, turns out I defo was and I’m now on patches and tablets, however, have problems trying to keep the patch on, I have it on my buttock area but if I have a night sweat (which have died down loads but I still have them sporadically) it falls off, I know I can’t use cello tape or glue so any ideas will be greatly received, thanks all
