A lot of people talk about the side of effect of these meds but it isn't just what happens when you're on the drug but what happens when you suddenly stop taking them. Withdrawl symptoms can be VERY severe and dangerous. I've seen first hand from a few family members and friends.
It is super common for a newly diagnosed person to start meds and then after several weeks decide they don't want to take them anymore because they think they're fine and don't need them. Next thing you know they quit the meds cold turkey and have severe withdrawl symptoms which often wind up being far worse than the symptoms caused by the initial diagnosis. It can get very serious, very fast.
