I take 225mg of Effexor daily, which I believe is classified as an SNRI. I am also tapering off of Valium - I'm at 10 mg of that a day.

I have been researching L-Theanine as a way to help me with the Valium withdrawal. But since L-Theanine is an agonist of GABA and assists in balancing and potentially increasing dopamine levels, not to mention that it appears to affect serotonin levels, is it safe to take with an SNRI?

I don't want to have serotonin poisoning.

Thank you.
