L-Theanine is great when combining with coffee, but at least for me when I've experiment with this combination, if doing it routinely, it really can start to deplete maybe the serotonin levels or something in my brain, because I start to feel more dull in a way, it's hard to describe, it's kinda like this slight fuzziness.

Just for more info, I've been experimenting with 200 mg of L-theanine combined with one cup of coffee. Not something I would take in long periods, but definitely useful for those stints where you just have to get something done and need the stimulants.

L-theanine is good also for relaxation alone, and calming the nerves down, I sometimes take it by itself if I feel too anxious also.

That's interesting, your findings are contrary to what's generally reported. I haven't found data confirming any negative side effects for l-theanine including prolonged use. I suppose it all depends on an individual and dosage of all stimulants.

Yeah, it's interesting to hear that people have no side effect. It's not anything really substantial, but there is definitely some side-effect. I'm used to being really sensitive to any substances though, for example I couldn't drink 3 cups of coffee a day, that would drive me totally hyper.

But after all, that calming effect has to come from somewhere with L-theanine.
