Dealing with ADHD

My sons are both taking ADHD medication. One thing I noticed is that they were getting wilder when they are not on. My youngest constantly eats all day. I used to give them their medication every day because I did not how to deal with them while I was working on weekends. Well, now I don't work when they are around me.
When I do my part-time gigs, I try to do it at night after they go to bed or when they went to their friends house.
I am learning to juggle my skills.
This week, I did not give them medication at all. They are wide open! But they are boys...I want them to have fun.
