Should be dead now.
If your liver is destroyed Isopropyl alcohol is lethal.
Isopropyl alcohol is surprisingly safe to drink. It's not good for you, but one can drink a significant amount before it becomes fatal. LD50 for humans is estimated around 250mL in an average size human adult. That doesn't sound like much, but it's lots. If you were drinking 40% concentrated rubbing alcohol, 250mL would be about 21 shot glasses. Drinking 21 shot glasses of tequila will kill you just as fast.
It has everything to do with the metabolism steps. You breath in oxygen, so it's fair to assume your body is oxidizing things. Without knowing anything about biology, the general rule of oxidation is to add oxygen atoms and remove hydrogen atoms from the molecule, and start with the carbon atom that is most positive because that's the side easiest to attack.
normal drinking alcohol
CH3-CH2-OH --> CH3-CH=O --> CH3-COOH --> further reactions
ethanol --> ethanal (acetylaldehyde) --> acetic acid (vinegar) --> further reactions
Acetylaldehyde is commonly found in food, and you already know that vinegar isn't poisonous. No problems here unless you drink lots in a short period of time.
wood alcohol (stuff that blinds you)
CH3-OH --> CH2=O --> H-COOH
methanol (fondue fuel) --> methanal (formaldehyde) --> methanoic acid (formic acid)
I don't know if methanol is bad for you, but formaldehyde definitely is. That's embalming fluid. Formic acid is an effective preservative, so it's probably a bad idea to have that inside your brain.
rubbing alcohol
CH3-CHOH-CH3 --> CH3-CO-CH3
2-propanol --> 2-propanone (acetone)
The alcohol itself is similar to ethanol, so that's not a big deal. You would think acetone is super dangerous because it's a harsh solvent used for stripping paint and nail polish, but it's really not. It's bad for you, but the body can deal with it.
