Sugar free Diet (ADHD)

My daughter is 4 had has to be on a sugar free diet. She has been diagnosed with ADHA. I homeschool and refuse to put her on meds. She has been to the hospital 3x last year for jumping off things. The last time I took her in for a follow-up visit the doctor said I need to do something. I had been asking him for alteratives with no help so I googled it and we remove sugar and dyes and WOW the difference!!
She has been a trooper as have my other kids with the change in diet but I need some ideas or recipes.
She LOVES chocolate milk and cake. lol This has been the hardest to do away with but maybe someone has a suggestion on how to make these sugar free. Also all the vitamins and meds (like Tylenol and cold meds) Have sugar in them and if I give them to her she goes bonkers. This is all new to me and I had no idea how much sugar my kids were getting!! Thank you in advance for any help
