Someone I'm close is a former CEO and majority shareholder of business that generated 8 figure yearly revenue. His advice to me was to "never hit the send button until the next morning". I'm inclined to give you the same advice.
Alcohol lowers your inhibitions and your sensitivity to the needs and feelings of others. It's a wonderful social lubricant but it also leaves you occasionally cringing the next morning as you remember what you said. Usually there's no record of it other than fading memory. Emails are on the record, so you may be cringing for a long time if you get it wrong and it could be expensive.
