I took shrooms (3.1 grams) a week ago, will I be good in a couple days to take them again? This time a full 8th. Is 10 or so days good enough for tolerance to go down or will the magic and fun wear out?
Your tolerance should be pretty low if not totally gone physically. But mentally you might not find the trip as good. You know what to expect and it takes the brain longer to forget.
How many times have you taken shrooms? was that your first time? Because i think 10 days is definitely enough time for the tolerance to go down but like others have said if you trip too often or close together then the experience will not seem as "new and interesting" to you.
Mushrooms are not good for long term. I used them weekly for about a year and found that they made me hallucinate and very forgetful. I do not recommend using shrooms or any hallucinigins for long. long term it will screw you up.
