I'm thinking not enough damage to accomplish what you're hoping for.
From what I could gather from reading a few poison control FAQs, most products are fairly non-toxic. You could get drunk off alcohol based products, but it doesn't sound like anything fatal. (Maybe over continuous use, but vodka would taste better and contain more alcohol). You'd probably get really sick.
Many products are much safer these days because people will drink things like hairspray or rubbing alcohol in large amounts to get drunk. Having worked security in the past, I've seen people get black out drunk on isopropyl alcohol and survive. In some cases, doing it for mamy years.
In the chance that you find something lethal, it would likely be slow and agonizing. Failing could mean some serious damage that will make you feel much worse than you do now.
Bleach or drain cleaner would be much more dangerous. However while those would likely fry from your throat down to your stomach, causing excruciating pain as it eats its way down, it probably won't kill you. But you will be damaged pretty badly.
