Method cinolazepam + alcohol + drowning?

[homeless]

Hey! This is my first post here so bear with me.

I'm being prescribed a rare kind of sleeping pills (cinolazepam). One time I tried taking 6 pills (240mg) and about 6 shots of strong vodka and I completely blacked out. I couldn't walk, talk or move properly. I don't remember anything, I heard from others. That got me thinking, how many mgs would kill me?

This experience also made me come up with a method of my own(?): saving up and taking 800mgs of cinolazepam, wait around 25-30 minutes after taking them, then drink a couple shots and lay down in a bathtub full of water. You wouldn't be able to hold your head up and drown. Is this realistic? Any advice?

I'm sorry if this is dumb. Thanks for reading.

I think the drowning might work but wouldn't doing the same but being in the position for a partial hanging and once blacked out released from your position and end up hanging work, like holding onto a chair till you black out?

I was thinking of that too, my bathtub has the perfect rod to tie a rope to right above it! Thank you for your answer
