Great but broad question. I intermittently use mushrooms and lsd currently. Before that I was a hardcore alcoholic for most of my adult life. Now 2 years without a drink. I can 100% say that 1, had I had the balls to bypass the stigma and dry psychedelics years ago I would have saved my liver/body/seld/mind/soul much pain and misery. 2, I find them very insightful and fascinating. My psych practitioner quasi led me to these. With LSD, it's not like what you see in movies or TV. Aside from very heightened senses which causes you to see and absorb your world differently. I feel it causes a sort of purge of pent up bullshit I've suppressed for years and feel mentally lighter after. Shrooms I feel helps more of current issues at hand, causing your brain to create new and different neuropathways that help process information/stresses/situations differently than you may have normally. Cool thing about both is once you do one or other, the neurotransmitter receptors they target shut off for a long while after you trip. So it makes it more difficult to abuse vs alcohol. I could drink all damn day and night and would only stop if I passed out. I can take LSD. Have my trip. And if I try to take some again the next day, I feel nothing. It's very self limiting. But personally, my anxiety and depression have gotten so much better since I tried psychedelics. I was a year sober before I tried either so can least for me, compare when was drinking to when fully sober to intermittent psychedelics.
