Lilmissy try and find a new doctor. One that specializes in ADHD. It sounds like his meds are not right for him. Although ADHD kids often will fall apart at home because it’s a place they feel safe and they’ve had to work so hard to keep it together at school all day, it sound like in your case when he’s coming off his meds he’s “rebounding”. It’s very common when a dose is too high or the med is not the right one for kids to have huge behavior swings when it wears off. There are lots of options so keep pushing until you find someone who will work with you to get it right and hang in there!
