I feel you. After my last phone broke I decided to get a dual SIM phone. I set up my phone to block all calls on the first SIM from any unknown number. I got a cheap second pre-paid SIM and essentially made it my 'business number'. On my android I then have it set up to 'Do not disturb' mode during sleeping hours. The transition was a bit more cumbersome than I anticipated, but after it was all said and done, I couldn't be happier with the outcome. My friends and family can get a hold of me whenever, and I no longer get calls from business/employer/etc unless it is in the allocated times I want.
