I think people also don't read the pamplets that come with medications, and then they are surprised about the side effects.
One of my daughters has brain damage, and I took her to a psychologist when she was three because she was having terrible temper tantrums. The first thing the psychologist started talking about was medications. I never went back to that psychologist, and at 9 my daughter is pretty well-behaved 90% of the time. (Still has the tantrums, but under much better control without medication.)
My other daughter has asthma, and I thank God for her medication. She would be dead without it. I do know the risks involved with her medication, and I am very careful about it. I just know that the risk without the medication is death.
