What works best with SSRIs and antipsychotics ?

Hello,

I’m new to research chemicals. I’d like to try something new, in the past i’ve done « classical » drugs before such as coke, mdma, speed, ketamine… But i recently started seeking help for my mental health and i got put on lamotrigine 250mg, abilify, prozac 40mg. I don’t want to risk a serotoninergic syndrome so i’m looking for safe alternatives that could still make me euphoric and make a wonderful trip

Thank you for your answers
