L-Theanine/caffeine stack causing insomnia?

[Purge]

Long story short, I took 400 milligrams of L-Theanine with about the same amount of caffeine early yesterday morning and woke up several hours earlier than I usually do today. I had to take Kava to get back to sleep. Anyone else experience this?

Theanine does not cause insomnia.

Never had that issue especially so far apart (morning dose and nighttime). Caffeine’s half life is a few to several hours depending on height/weight etc so it should have been eliminated by then. Any other source of caffeine etc later in the day?

No, that was it.

Theanine won't have any role in you waking up as it's a supplement that will actually calm you down. While caffeine's active an effective for only a few hours, the effects of caffeine can last much longer. While you won't still have energy from the caffeine in the evening, it still can contribute to restlessness or not as easy to calm yourself down before bed.

Theanine increases alpha waves so it is not a stimulant on it's own.

Come to think of it, I was drag-ass at work for a good part of the afternoon. I'm thinking my sleeping schedule is off. I'll cut back on the stimulants for the next couple of days to see if that helps.
