I have. It's awesome. Just as good as mushrooms if you ask me. I had it in 30mg pills and Id say that was equivalent to about 2 grams of mushrooms. I tried it 4 times and had 6 pills so a few times I took more than 1 pill.
You can also try 4-HO-MET - sort of "lighter" and "easier" than 4acodmt. Also highly recommend 2-CB if you can get your hands on any. It's like the best parts of LSD and MDMA combined into one, without the MDMA "hangover". Invented by the legend Alexander Shulgin.
