Is it me or does tea have a remarkable effect on Consciousness?

I often drink a cup of Tea before bedtime as it relaxes my body and calms my Mind while at the same time it clears and sharpens my mind andpotentiates it's attention focus. Whenever I try any specific LDtechnique I also often drink Tea before sleeping as I can see how Tea's effects can be desirable to experience while asleep and Dreaming in respect to having Lucid Dreams.

Maybe in time I have put more and more faith in Tea and this is how I can drink a Cup of Tea and really experience how it washes away the dullness and thought-chaos in my Mind leaving me Calm but very mentally awake and aware.
Peacefully wakefull in a way I can easily sleep. I don't know to what extent this is my ''Idea"about Tea (Placebo) or what Tea actually does. I am a real Tea-o-phile I should admit. However Tea is stimulant as it contains Caffeïne and Theïne which is why alot of people drink it to become more awake in the morning when they feel really groggy.

Anyone else noticed this?
Maybe if Tea has these properties it would be a good Idea to consume ALOT of Tea about an hour before bedtime; being able to take a seriously long leak before going to bed.
