kratom and tryptamines

[snapper]

SWIM wanted to ask other SWIM's experiences.
SWIM recently wanted to do some 4acoDIPT. SWIM took 20 mg after work, where SWIM had taked about 3-5 g of kratom 6 hours earlier. SWIM ended up having a horrible 4 hours of uncontrolled tremors and nausea. This has never happened before. SWIM has also noticed that kratom makes some tryptamines wear off faster and some not work at all. SWIM has so far not had trouble with PEAs and found kratom to be a good choice on the comedown for the hallucinogenics SWIM has combined it with.
Has any SWIM had a similar negative reaction. SWIM also had bad time on 2CBFLY (which previously SWIM enjoyed) and thinks kratom may have made it unpleasant too, though not to the degree of the 4acoDIPT.
