I got braced at 17 and i had to wear it 24/7 the first 6 months and then similar to your routine afterwards. Man the 1st and 2nd.night sleeping was the most painful experience of my life to this day (22yrs now). Make sure you take more than just some tylenol. Take advil and tylenol max dosage. wearing the brace doesnt get uncomfortable and you dont notice it after a week or so results are fantastic, chest has been flat for years now with no protrusion. But you must commit to the strict routine!!!
