Is 1 egg and 1 cup of tea enough?

for breakfast

yes

I usually don't even bother eating breakfast for most of the time.

Caffeine 😋

I'd recommend a slice of bread or some form of carb to go with the egg/cup of tea (you could try a biscuit).

I drink 1 coffee for breakfast 👍

I dont have breakfast usually but I think thats good enough, I dont really like eggs tho
