Ha, that was me that asked the snarky "Drinking Problem" question.
Honestly, I feel great if I don't drink. I sleep better, wake up early, exercise and feel energized and focused in the morning and throughout the day.
If I have a couple drinks at night (couple glasses of wine or 2-3 gin-and-tonics), I sleep with more restlessness, sometimes sleep late, and feel a slight difference in the morning (less focus and energy).
If I go bonkers and drink a bottle of red wine or 5+ cocktails...then I usually wake up later, usually sleep shitty, wake up with a foggy mind and sensitive stomach. Writing and debugging code in this state is a bitch.
I wear a fitbit that monitors my heart rate and measures restlessness during the night. I definitely notice increased restlessness AND about 10-15 beats per minute higher heart rate during the night after even just a few drinks.
So then after a day or two and at night, I think "hmmm a drink sounds nice"...
