Ashwgandha, Bacopa and Gotu Kola

I'm making a stack with the ingredients Gotu Kola, Ashwagandha, Bacopa, Dried Ginger, and Lemongrass. In what ratio should I combine these? I have 1oz of each and thought to play it safe with something small. My reason for taking this mix of herbs is a follows: I have read up on the Ayurveda herbs and the effect they have on memory, cognition, anxiety, depression, and the antioxidants they contain are profound. I was taking clonazepam(Klonopin)for 7 years for a very crippling social anxiety disorder and felt myself losing my mind. I was also an alcoholic consuming a 12pk a day of 6% abv. Really! I would compare my CNR to that of a person with alzheimers. Not even a joke. My memory and other functions were that bad. I have been off those for between 3 to 4 months now and my brain is healing slowly. Can be up to 2 years for a full recovery. I am also taking Tegretol, which I am stopping this week, and Clonodine for sleeping. I so badly want to replace and stop taking prescription medication. I am also taking 2mg of bupenorphine a day too. Its time to make myself healthy and this is a good start but I would like all the input I can get on the correct dosage for these herbs. I am planning on infusing(brewing tea)these 3 times daily. Can I make multiple infusions throughout the day? Also, I hear that these make a person a bit tired. Should I put something else in this stack, i.e. yerba mate, oolong tea...., or just drink my mate and tea separate? I am 150Lbs. Tweet
