Alcohol wd

If I’ve been drinking about 3 16oz IPA 9.5% alcohol a day for about 4 months, will I have withdrawls? I stopped for a day but when I did I couldn’t sleep the rest of the night tossing n turning so I just kept drinking but I’m tired of it. If it’s only 1 night I feel I should be fine…I heard withdrawls from alcohol are something not to mess with, so I’m just curious. I have all the electrolytes and just got some celtic salt and vitamin b, Trying to be ready.
