I totally sympathize with you. I can remember being where you are now and it was very frustrating and stressful.
Maybe some of this will be helpful.
Nebulizers that are newer can reduce the time they need to sit. It used to take us about 20 minutes to administer a full treatment now with the newer compressors its like 5 minutes.
Get some longer tubing and move the machine far away from him. The noise the machine makes could upset him. We used to hide it too.
When my son was old enough to reason with we made up games that involved him having to wear the mask, called him super hero and space characters.
When he was out of sorts and really sick we especially needed him to stay calm so when he fought us we did not force the mask issue and we placed the tube at his mouth and nose and I cupped my hand around it. It does work!
I always read to him his favorite stories or we watched his favorite movie. I also allowed him to pick a treat for after the treatment and he looked forward to that sometimes. I would have small surprises kept in the house as rewards.
Remember when you get uptight they do too! Try your hardest to not let him see you stress.
Sometimes he would cry through the whole thing and I learned that when crying they grab more air and more albuterol as well.

Tears are not always a bad thing.
Also try holding him in your lap prior to the treatment sometimes that relaxes them enough to get through it.
Eventually they comply

It takes time and soon they just know its helping them and they need it.
What kind of nose drops? My son was on Nasonex and I would just lay him down and kinda just do it no warning since that worked him up tremendously.
My son had/has issues with liquid oral medications and would immediately vomit after getting the dose into him. Finally and it was ridiculous the only thing that worked was administering it with a dropper into his cheek bit by bit over a period of about 1/2 and hour. I was Queen of mixing it with whatever the doctor said I could to disguise the taste. Eventually he learned at a VERY early age to swallow pills and thank God for that.
If I think of any other things that may help I will post again! You are not alone. Hang in there Mom it will get better.
