Wondering if you can overdose on the 3 put together. And if you can, can you die?

Most likely you will be found convulsing, vomiting, and it lots of pain, with swelling, nausea, and even possibly some long term effects that will not kill you but will be bothersome. Your stomach may be pumped and you may be given charcoal or have your stomach washed out. You may be committed to a hospital for up to 15 days. It's one way to get help, but there are better ones, such as walking into an outpatient clinic and saying you are depressed enough to want to die.

If you are basically young and healthy it takes much, much more to kill yourself than if you are elderly or have cancer, AIDS, etc.
