Why now I can't sleep with coffee/colas?

[big_boy_1]

Some years ago coffee / cola drinks had no effect in me.

But since I started using a bit higher doses of testosterone (750mg-1g), I can't sleep if i take them after lunch, or worse yet at night.

Why?

All AAS have a stimulant effect on the central nervous system.

I don't know that it's the caffeine keepin you up. My first two times around with juice I had insomnia pretty bad. My money is on the juice. I must say though, that as I've gotten older, OTC fatburners hit me harder. No problems with diet soda though. I usually drink caffeine free anyway to try and keep well hydrated.

as you age, your sensitivity to caffiene will increase. the mechanism may be tied in to hormones (im not sure never had a reason to check), but one way or another, thats the pattern.

i get lots of patients complaining that they cant have a coffee in the evening anymore without taking a sleeping pill...but then, i dont mind, since i dont own a coffee shop, and, uh...i sell sleeping pills
