I'm afraid I only tried the Yueju for one day and gave up - I lack patience. I have 5 more bags of it to make into tea- anyone in London want it?! I can't post it, but could hand it over in person in central London sometime. Or I am in Feltham (or Hendon, my former marital home till recent separation)...
I do also have a single herb - Zhi Zi (Gardenia Fruit) which has good reviews. I have only tried this once, but I will try it more consistently and report back to all of you.
At the moment, I have been put on Lyrica which has scary side effects, but is helping me feel better - well I feel as high as a kite.
The other thing that was quite good was Tianeptine Sulfate (which apparently rebuilds your brain). Kratom there are some folks it helps (not me, but some say it is life-saving), microdosing LSD. There are also other Nootropics, Fasoracetam, Selank, Phenibut - I have heard good things about them on Reddit.
All I can say (if I may) is fuck depression. I wish I had a cure for all of us - I will keep you posted on the Zhi Zi.
