Well... There are much pills on the market, but the deadly ones are changed to safer ones.
Would not consider pills a good way myself.
Unless you can get antiemetics+amitriptyline (which does not guarantee peaceful death), antiemetics+phenobarbital (not easy to get in such an amount), Propoxyphene.
There is an option also to take Morphine Sulphate, Chloral Hydrate(liquid) and Phenobarbital. but a little bit more challenging.
Another option: Diazepam + Digoxin + Propanolol + Morphine Sulphate (very peaceful altogether)
if you want to get some more information, please, read Peaceful Pill Handbook and use this forum to do as much research as you can.
Maybe you will understand that pills are not for you
Please, take care
Update: The newer version of Peaceful Pill Handbook, the better it is. You can find it searching in zlibrary(just google it) (March 2019) or find a link to download 2019 December version here, on this forum
