That dose is an outrageously huge starting dose. When I was started on it, I took 2 mg twice a day for the first 3 days and then 4 mg once a day after that. Two years later, my dose has been slowly titrated up to 16 mg (8 mg twice a day), and honestly, I couldn't even imagine 8 mg 3x per day and how sick it'd make you feel. At that dose, chances are you'd get some brutal headaches as Suboxone can cause them, especially during the initial phases of treatment or after dose increases, IME. Tricomb is right about twice-daily dosing though, until recently, I used to take 16 mg once a day and would actually get withdrawals within 16-18 hours of my morning dose. Since switching to 8 mg twice a day, I don't get the withdrawals and I've noticed fewer side effects.
