I realize your son is older, but I would look into providing sensory breaks for him. From my experience, most kids with ADHD have some sensory issues. Those were the first thing that presented with my oldest, but his are so similar to mine that I thought they were normal. They weren't. Most people apparently don't have foods that make them vomit. I do. So when my son reacted that way to tomatoes, I didn't think it was a big deal. He wasn't allergic, he just vomited if he ate much tomato anything. Years later, I learned about sensory issues and thought we could have done a ton when our son was younger if we just learned about them.
Luckily, kids usually like sensory therapy. They generally enjoy the sensory activities that help them, and it can actually work to calm them. You can learn more about sensory issues, therapy and disorder with the book "The Out of Sync Child". I strongly recommend it, and another book by the same author, "The Out of Sync Child Has Fun". The Has Fun book is packed with activities to provide various types of sensory input. My family wore out more than one copy of this book through regular, enthusiastic use. It was fun for everyone, not just kids with sensory issues. We would end up iwth every kid from 4 to 18 in our backyard, with their parents, all doing an activity from this book. I swear the other kids could sense it when we took the book out, because they would just start appearing at our house. This was, of course, many years before the pandemic. We ALL had fun with so many different activities. Some of the teens had already started to get into big trouble, and this was a time when their parents knew they were not out getting into trouble, just having fun with a big bunch of people.
I would get the Has Fun book and see if there are activities you can do with your son, or ones that would provide him with a sensory break. Having a sensory break can help get energy out (if that is a need), it can provide deep pressure if needed, or oral stimulation or pretty much any sensory input that he wants/needs. Kids are drawn to the sensory activities they need. My youngest son used to do his reading and tv watching while sitting upside down on his head on the couch. As long as he didn't stick his feet into anyone's face, it was find with me. I just thought he was a strange little kid. in my opinion all little kids have their quirks. Turns out, he needed deep pressure on his head. It was totally a sensory thing and we just didn't know. Just like his refusal to have any sauce or dip or dressings on his food (except salsa). He doesn't like the texture of most sauces. A sensory thing. Being a very picky eater (far pickier than my kids), I just made his food and left whatever sauce we had off his portion. I didn't think it was a big deal, but it was. It was providing a sensory need for him by not forcing him to eat sauces. It saved a LOT of fighting.
I realize your child does not have a diagnosis of Sensory Integration Disorder, but sensory activities can still be a help. Take his dislike of clothing. Ask if it itches him, or how it bothers him. Then you can work to find a solution. I cannot wear anything that itches. It becomes the focus of my mind and I literally am unable to think of anything else while I itch. As a child, an aunt dressed me in those ruffled panties that some people think are cute on kids. I cut the ruffles (and a strip of the underwear with each one) off and then ptu the pants back on. My aunt was furious, but my mother would not let her yell at me. My mother's kids did not EVER have to wear itchy clothes. If the only options in stores was itchy, my mom would make me clothes that didn't itch. Thank God. Itchy clothes drive me up the wall, and it had gotten worse as I get older. MUCH worse.
I learned in time that all my kids had reason for the things they did that drove me nuts. By finding out why they were doing those things, we could find ways to deal with the problem without fighting. So you have to ask, what does he get by jumping on you and waking you up? How can you provide that at times when it is appropriate so that he can not bug you in the middle of the night?
