Inducing lactation without medicine, is that possible?if not how to manage side effects?

I've been into lactating personally for a long time and tried all the methods including taking pills, well nothing was more effective than that but it came up with side effects like laziness, brain fog and controlled bleeding during period. You can tell it affected my performance at job and overall health but because of my busy life, I don't have any other choice than taking pills so does anyone know how can I minimize the side effects and keep making milk? Me and my partner both love how it looks to leak or spray milk from my boobs during sex, I have a strong urge to be full and sucked too so I want it deeply
