Coffee in the morning?

Textronic

Hi

Could coffee before 10-30 am affect your sleep that nite?

I'm a light sleeper but don't want to quit either

I drink coffee daily Textronic. Builds tolerance. No sleep problems for me. But also exercise daily. Avoid eating late. Have lots of Hans Selye eustress (due to university demands), but very little distress (harmful). People are different. Have individual differences.

Decaf?

I normally have about 6 cups of coffee a day. Last one about 7pm and have no problem sleeping when I go to bed about 11.

Can’t imagine how a cup in the morning could effect night time sleep. Maybe if you had a cup at 22:30 might be different

High caffeine tolerance heroics? Built up over time. Mine's low. I do 2 average daily. Except exam crams. Then what it takes.

I drink about 5-7 cups a day or 2-3 and some tea

My latest would be 6pm and no issues sleeping from 10:00pm

Highly 1 cup before 10:00am would affect you

Know of a workplace. Free coffee for employees. But no decaf. Boss pays for caffeine-driven folks.

Caffeiene has a half life of 6 hours and most people tolerate around 400mg (4 cups or 2 and a bit medium cappuccinos) a day very easily.

So if you drink one at 10 am and one at 2pm with 150mg each in them you'll have >100mg in your system at 1pm, nearly 300mg at 2pm, and 150mg left at 8pm.
By bedtime, you'll still have a small amount keeping you wired.

All the above scientific stuff said, I drink 2 or 3 coffees a day including often one in the evening and have no trouble sleeping. In fact around the same time as I started drinking coffee I switched to a 9 to 5 job and have slept much better generally in those few years.

Volunteered last summer. Worked at a center for folks with progressive disease that destroys memory and other important mental functions. One to two cups of coffee per day encouraged.

I would have a high enough tolerance all right. I suppose it also depends on the coffee and the size of the cup.

For example

237mL of brewed contains 95-165mg of caffeine, an espresso 47-64mg and instant 63mg

Or you could be having a Starbucks Coffee, Blonde Roast venti (590mL). with 475mg of caffeine

I know its US based (everything in stupid OZ) but for example

Doubtful if a morning cup would affect evening sleep.

I avoid energy drinks. Even if made with coffee.
