The supplements I mentioned are all about 10-15$ per 60ct bottle on amazon, which would last about a month. Are you entirely med free right now? If so the Sensoril would be best to add first. I've found that l-theanine tempers my hypomanias even though it potentiates my amphetamine.

If you're under a lot of stress which is affecting mood then chronic administration of theanine (200mg 2-3 times a day for three or more weeks) may further protect against stress induced episodes. Just make sure that you're getting Sensoril and Suntheanine in the bottle. I'm not sure whether or not there's much of a difference in taurine based upon brand, but the stuff I've gotten from Thorne Research works well.

There's a lot of useful information on these substances on examine.com.
