I take codryamol (dihydrocodeine & paracetamol) to take the edge off.
HRT definitely rewrote my neurology as I never felt pain in the past but now I'm hypersensitive. Worth keeping in mind as I used to happily doze off into a restful sleep without even a twitch for 4 hour sessions of electrolysis. Those days are long gone. I love that I can feel things now but wow pain really sucks.
Only 2 real tricks I've found that seriously help me.
The first is as I near breaking point I remind myself I need & want it and that each zap is another step closer to the end; this is enough to suppress the impulse to scream and run keeping me focused.
The second I can't really control but I've found there is only so much pain my body can handle before it kinda overloads and puts me to sleep.
Ok now I've made it sound like a nightmare that's not good........ but as bad it gets I still look forward to next time
Like many things it's a means to an end and it's finite. That makes me happy about it all
