The antidote to methanol is just ethanol.
If you find yourself drinking something untrustworthy you can at least cure yourself with a chaser of an equivalent amount of everclear.
While the treatment for methanol poisoning indeed includes ethanol, I don’t think your dosage suggestion is right. Your body would still have to process all the methanol, the job of the ethanol is just to slow down the reaction. If you suspect methanol poisoning you need the hospital, they will administer the ethanol intravenously and I think do dialysis to remove the methanol and the formic acid it metabolizes to (this is one of the toxins in ant venom)
you are saving lives, friend.
The way you're saying it is deeply irresponsible. The way to deal with methanol poisoning is not "just ethanol", and you cannot "cure yourself" by drinking everclear.
If you ever find out you have been drinking methanol by all means do drink safe spirits if you have immediate access to them (after throwing up what you can if you're still in time), but get medical help now. Ethanol will not cure you from methanol poisoning, it will only help reduce and delay the damage somewhat while you're waiting for an ambulance or making your way to a hospital to get proper treatment.
