On: Ask HN: How many coffee do you need per day to get your work done?

I have two double shots of espresso and one tea all before midday as I found caffeine after midday was causing interrupted sleep with vivid dreams.

I was similar to you in that ive given up coffee but found I was unproductive without it.

I've found the before midday approach has worked well for me.

Same here. Any coffee after 3pm would impact my sleep.
