Really help with adhd

My 8 year old had severe ADHD and we've been trying to help him without those harsh prescribed drugs. We go with more natural ways he eats a certain diet and also we use essential oils but the worst task we've found is how do we keep his hands and mind busy because he fidgets so very much and then we came across DrowseBuster fidget spinner and figure hey I'll give it a try this fidget helps him so much it is unbelievable! Unlike other cheaply made fidget spinner the bearings actually stay in place don't don't slide out which was a big deal for me I'd rather a toy stay together so no child chokes
