4-fa and mdma

recenrmy got in to 4-fa done it a couple of times and it's unreal i highly recommend it.

off to glasto and i can't be dealing with getting on mdma more than once a week anymore so was going to do pills (skypes/ikeas) one of the nights and 4-fa on another night, i get that whatever one i take last will have diminished effects but does anyone have experience or advice on what order to do it?

My original plan was 4-fa on the thursday, just get ketty on the friday and drink a bit, get pilly on the saturday then 2cb on the sunday. this would all be with bumps of ket thrown in & occasional drinking.

TL;DR: do i do 4-fa a few days before or a few days after mdma and is it even worth doing if the effects will be much lower.
