I recently started taking L-Theanine and caffeine (mostly via coffee, but I occasionally use caffeine powder). It seems to give me some solid focus for a few hours, but to be honest I'm not sure if it's a placebo effect.
Same here, I couldn't tell if the focus was from the L-Theanine or placebo. Unfortunately I'd also get a terrible headache many hours later and have my sleep disrupted (again, hard to tell if it was placebo or not).
I still have the majority of a bottle left, so maybe I'll skip the caffeine and give it another go at some point.
Yeah, I take l-thenaine + caffeine in the morning. I can't drink coffee since it seems to give me acid indigestion in the morning but caffeine pills are the perfect substitute for me.
Keeps me alert and awake in the morning, which is when I tend to have the least motivation.
