To break it down for you: it would be safest to not use any drugs at all. You have been prescribed a lot of meds for a good reason I suppose. If you still decide to take LSD, then some of these meds will reduce it's effects to varying degrees. Stopping an antipsychotic doesn't sound like a safe plan, even temporarily. Prozac needs to be gradually tapered down over a long period of time. And slowly built up again afterward. Then there's the mental health risks of tripping itself, especially for someone who needs all these meds. We cannot decide for you wether to take LSD or not, but if you come asking here for harm reduction advice, the only sound advice we can give is that there's an increased risk in your situation. It would be wise to wait until you're mentally stable without the need for these meds. Maybe that's not possible in your situation. In that case it would be safest to not use any drugs at all.
