Turning it down?

So I’m on 300mg lamictal 4.5 vraylar and 10mg vilazadone plus 60mg of adderall I’m not enjoying the side effects I get from working hard. Turns out when you exercise heavily your body digs into your reserves of antipsychotic and boy I get fucked up when I work hard. Is there a way for me to lower my dosages. I’ve only had one manic breakdown that’s recorded and i have no criminal history. When I broke I broke hard but I think managing my bipolar looks like me lowering my meds but how should I go about it I like my mix but its a bit too much and I think I’m relatively safe without so much medication. Any advice or resources would be appreciated. I’m from Idaho and my resources are lacking and I’m a broke bitch.
