is this combo too crazy?

ok so i had a theoretical idea to use mdma, weed, pregabalin, and ketamine all in the same night. i dont see any interaction issues (other than possibly the pregabalin and mdma but i made a seperate post about that) and just last night i combined weed, pregabalin, and ketamine and had an awesome time (i barely remember it but it was very interesting apart from when i fell asleep lmao) so im thinking maybe mdma would make it better? i’d have to try work out the optimal timing for all the peaks to coincide but like idk i think it could be fun, thoughts?
