sounds like you too the meds without going overboard. I suspect you did not become addicted and therefore would have very mild if any withdrawals. Good for you! I hope your shoulder heals well!
Have you ever detoxed off of opiates before? I ask because the more times you detox, the worse/longer the symptoms. 7 months of daily use is definitely enough to form a physical dependence. You were on quite a low dose, so if this is your first time detoxing off of the medication you can expect minimal symptoms.
Congrats on day 3! Keep up the good work
