A good friend of mine tried microdosing mushrooms for these issues, and it made his anxiety, panic issues, and depression 1,000x worse and he had a horrible bad trip from it. He wound up having to go on a low dose of benzo drugs, and just drinks and smokes weed and hash now. He said had he known a micro or low dose of mushrooms would have affected him this way he would have just taken a larger dose of Psilocybin mushrooms and really tripped.
I have taken moderate, low, and micro doses of LSD. It was not for anxiety, depression, etc. I did it because I had already experienced a super high dose of acid and wanted to see what lower doses were like.
At micro doses LSD is like a stimulant in some ways, not like Amphetamine, cocaine, or even coffee or tea, but more like large quantities of yerba mate as they both give you euphoria and colours turn brighter, but again a micro dose of LSD is not really a trip.
I did not always have access to Psilocybin mushrooms so when I would take those I would get them in bulk, eat 2.0g which gave me a ++++ experience with telepathy, or 1.5g for a +++ experience. I know people grow them but everything has to be super sterile and when I was into using drugs I had dogs and cats, and later I lived in a city with lots of narcs and someone I knew was growing mushrooms, selling to friends and got arrested and went to prison for cultivation, dealing, and using a communication network to sell drugs-this was via pager, and simple email long before texting and mobile phones.
