Actually, telling that reminded me of a play session with my former (soon ex-former, he came back and tied me up a couple of weeks ago!!) playmate, also a CD. He'd been hurt doing some physical fitness thing, yanked a muscle, and was on muscle relaxants that he said always made him sleep.
I didn't go for the idea at first, but it was time for him to take one anyway. After getting dressed he took a pill, we went to the basement where he was gagged and hogtied, and as I tied her up she was feeling the effects of the medication. I made sure the knot on the wrists was easy to get out of, we'd been tying each other up for years and we both know how to tie up the other so she can get out after we leave her.
Debriefing some days later, my friend told me he'd panicked for a moment after waking up, then remembered what happened, and enjoyed a good struggling session before getting free.
Ever since then I've wondered about trying it myself, but I don't think I ever will. That's just me
