Comment:
The effective dose of alcohol to cause 8.1.4.1 Immediate alcohol-induced headache is variable, and can be very small in people with 1. Migraine (who, at other times, may tolerate alcohol at the same level as non-migraineurs). 8.1.4.1 Immediate alcohol-induced headache is much rarer than 8.1.4.2 Delayed alcohol-induced headache.
