Thinking about getting rid of tablets entirely until high school

Been reading a lot about how screens are affecting kids' attention spans and sleep and honestly I'm getting pretty concerned. My wife thinks I'm being reactionary but my 9 and 11 year old both sleep better and are less moody when they're not on tablets. Thinking about just removing them from the house except for maybe weekends. The backlash will be real but sometimes you gotta make the hard call as a parent. Any of you guys actually gone cold turkey on home devices? What was the adjustment period like?
