Help What is a good drug combo that will force me to sleep? Need for my CTB method.

I have made a "device" that, once triggered, will activate after one hour and will ensure I never wake up again. The reason for the hour delay after being triggered is that I want to be asleep once it activates. I attempted with it last night in the middle of the desert, but my drug combo failed to force me to sleep as I am not experienced with drugs in general. I took 120mg of codeine (4x #3 codeine tablets) and 15ml of promethazine (would have taken more but that's all I had). Any ideas what might be a good combo that would make it impossible for me to stay awake? I don't really have access to anything besides codeine, alcohol, and basic things like benadryl & nyquil. Nyquil does tend to make me very tired. I still have a good amount of codeine left, (5x #3 codeine tablets and also some codeine cough syrup). Thanks :)

Some heavy antipsychotics are usually good at that, but need a prescription.

Maybe if I mix a bunch of codeine and alcohol, and maybe even throw in some nyquil? Lol. I'd experiment, but I don't want to waste any codeine.

Bump. Anyone have any experience with this? Just wondering generally how much alcohol and codeine it would likely take, and about mixing in a 3rd thing like benadryl or nyquil.

Edit: Also, I am very skinny and don't really have any tolerance to opiates/alcohol.
