Is this good enough?

[Pisceslilith]

I have 48 naproxen, 9 odansetron, and a lot of Zantac. I also have valerian but I don't think that would help much so I don't think I should add to it. My other method (which I'm starting today by the way) is to stop eating and drinking. See what happens. Would any of this work?

I wouldnt count on any prescription medication to OD, they are made to keep customers alive.
Death by dehydratation is fairly long and unpleasant your survival instinct will make you drink eventually.
If you want to ctb there are better methods just search the list of resources in main thread

No, but it might land you in the hospital. OD's are extremely unreliable and as stated above, it's more likely SI will kick in than it is that you will die of not eating/drinking, so I really don't advise any of this. It would likely just make your situation worse.
