mixing isopropyl alcohol and ethyl alcohol?

I’m going to a party but don’t know if regular alcohol will be supplied to me- everybody is bringing their own alcohol. it probably is going to be offered but just in case I have isopropyl alcohol. I’m wondering what the dangers are of mixing the two. if i recall correctly the way to counter act an iso OD(or was it methanol?) is to drink ethyl to get your liver busy processing that instead?

I’ve drank isopropyl alcohol before and know it gives you shit hangovers and is dangerously potent. but I’m wondering if there’s added danger to mixing the two. was thinking of pregaming with iso in case alcohol will not be supplied to me.

yes I know I’m a degenerate fiend please keep any un-helpful comments to yourself.
