Let's forget all the good arguments already given elsewhere and look at this from a logical/strategical perspective.
There are two options.
A. You are right about this B. You are wrong about this.
In the A scenario where you are right and there actually is a giant conspiracy based on publicly unknown advances in technology, you have the option to take the meds anyway and lead a normal and fearless life until the counterrevolution happens and you might be used against people, if it actually comes to that, or you can refuse to take your meds. However, since you are schizotypal, that would imply not being able to trust yourself and not being able to lead a functioning life until the day the counterrevolution happens (if it comes to that) when you might harm others and/or get killed in the upheaval yourself (both of these thingsmight happen anyway in a civil war scenario, even without robots controlling you!). Not only will there be little profit from not taking your meds, but there is a chance you might just as well be hospitalized because you can't fully function without your meds (just as somebdy with diabetics needs theirs).
In the B scenario you are having false fears that are caused by not taking your meds and those fears keep you from taking your meds. It's a vicious cycle. Your brain is playing tricks on you and keeps you from getting better or letting well-intentioned people help you. If this scenario continues long enough, you might end up hurting yourself and might end up being hospitalized for your own wellbeing because your condition will worsen more and more. They will force you to take your meds until your brain recovers and you will realize all this.
Alternatively, you could decide to make that leap of faith, take your meds again and hope that things will get better and the fear will disappear. There is a very, very high chance that'll happen.
So we have 4 scenarios
A1 - you are right and take them anyway - you eventually lose the "game" after years of comfort (0.5)
A2 - you are right and don't take them - you eventually win, but at a very high price (0.5)
B1 - you are wrong and take them - you win absolutely(1)
B2 - you are wrong and don't take them - you lose absolutely (0)
Let's assume for a moment that there is an equal chance of you being right or wrong. In that case the expected benefit of you taking the meds either way would be 0.75. The expected benefit of you not taking them would be 0.25.
So, mathematically speaking, even if there was a 50% chance that you are right about your suspicions, it would still be smarter to take your meds. It is 3x as beneficial to you even then!
And that is just the scenario for a 50-50 chance. Most people here will tell you the chances are more like 99.9999999999999999999 to 0.0000000000000000001
Also, with or without schizophrenia, trusting something you "just know" by intuition, not as an empirically proven fact is always a very shaky matter for any human being. If you are not sure about something due to your condition, asking if you know it by intuition or by fact might be a good litmus test. Your intuition is your own worst enemy, prplchknz!
