Hello, I intentionally overdosed as an attempt at suicide on two types of pills, and so far I feel fine. The first one was Cetirizine HCL and I took about 700mg pills. I waited 5 days and it didn't take into effect, besides feeling a little nauseous for a few minutes on day 3.

The second one was Acetaminophen (Tylenol) and I took about 6g of them (18 325mg) which was just a couple days ago. Again, I currently didn't feel anything more than a little bit of nausea.

I'm pretty sure my liver's messed up now, but does it take longer than just a few days for the effect to take in? Is it possible that I'm somewhat resistant to it, the pills weren't strong enough, or is there another explanation?
