Given the greatly variying potency of homegrown shrooms I'm not sure making a flat rate dosage reccomendation is the wisest thing...
Mabye I'm oversensititve to the effects but for me personally taking more than 2 grams of shrooms at the same time would initialy be a very uncomfortable experience.
I'm sure the discomfort and naseua would probably pass after I writhed around in a fetal position on the floor for about an hour and a half but I don't see any reason to put myself through that really....
I have found that taking a small amount of mushrooms and then waiting till stomach discomfort/panic and naseau pass and then once I'm in a comfortable zone I take the large doses that was there is not a super rough entry into the spirit realm...
Of course the shrooms I have tried are not anything anyone would want to take 7 grams of....
My advice if you want a smooth +4 experience is to take a litte shrooms with alot of Ayahuasca. I have also had great results small amounts of with mixing SUN DRIED amanitas with psilocybin...I have to emphasize sun dried because this is the only kind of Aminita that actually works.
And why do you look at the speck in your brother's eye, but do not percieve the plank in your own eye? Or how can you say to your brother, "brother let me remove the speck from your eye", when you yourself do not see the plank that is in your own eye?-Yeshua ben Yoseph
