Upon receipt of my Dainely Belt I wore it straightaway, cause that's what I bought it for! Wear it in the correct place and you instantly feel 'safe' and 'secure'. Not too much compression and you may keep it on all day. I have not slept with it on as within days I started to feel pain free, and that's how I am now, a month or so later, still pain free. I am not wearing it daily, however, the knowledge that it is at hand, makes me a happier person.
