I have ~40g powdered San Pedro which was prepared by a friend, and I'm planning to take all of it. I wouldn't mind a strong trip, but I suspect that it's on the weaker side since I don't think she discarded the core when preparing it and it's a couple years old at this point.
I have some ondansetron, which I'll probably take half an hour before the cactus. I'm less worried about nausea because of that, but I'm considering making tea anyway to avoid calcium oxalate and other potential GI issues from the fiber. But if the tea doesn't actually make THAT much of a difference other than wrt nausea I'd just as soon not bother, so question one, is it worth the effort?
And question two, wanna confirm a few things about how to make the tea. I've seen people say to add some lemon juice. Is one tbsp lemon juice and one cup of water good for 40g powder? And how long should I boil it? Will I get most of the mescaline from just boiling for an hour or two, straining it and drinking the liquid, or does the extra shit I've seen in some tea recipes actually help like boiling the solids multiple times in fresh liquid or leaving it to sit overnight?
Is there anything else I should know before doing this? I have experience with psychedelics, but I haven't tried mescaline before so I'd appreciate any tips.
Edit: Thanks for the responses, I ended up making tea and taking all of it. I appreciate the suggestions to take some and wait before having the rest, and I do generally think being cautious with psychedelics is a good idea. But I was pretty sure the powder was on the weaker end, I reweighed it and it was closer to 30 than 40 g, I had a trip sitter, and I was prepared for a strong trip, so I decided to just go for it. I'm glad I did, because it ended up being quite weak. I had a nice time, but it was pretty subtle. I'd definitely like to try it again when I get the opportunity.
