I've been experiencing a difficult withdrawal from Temazepam the last five months. I've found Ashwagandha root extract (Sensoril) and L-Theanine (Suntheanine) quite helpful in allowing me to cope. I take 200mg of Sensoril with each meal and space out 100-200mg dosages of Suntheanine throughout the day in about three hour intervals relative to the times my withdrawal is the most severe.

I found that neither of these supplements will directly alter mood the way a Benzo does, but rather attenuate the severity of how stressful an event is. It takes awhile for the Sensoril to start working, so it's effect is subtle, however the Theanine provided both immediate and extended benefits.

The upper limit of dosages for Theanine is ~800-1000mg, best to start small and not rely on it like a crutch imo. For Sensoril the guidelines are more flexible, but it takes weeks for it to start providing significant benefit, so again, start small (I used 200mg twice daily for over three months before increasing).
