Hi, It would have been easier for you to have tapered morphine further from 30 mg per day to less before stopping. That would have reduced the withdrawal symptoms. Now that you have been off morphine for more than a day, you need to hold on for a few more days. The usual symptoms are body ache, running nose, sneezing, watering from eyes, sleep difficulty, nausea, dilated pupils, restlessness, loose motions etc. This will be gone in a week. Till then, just remember to take lots of fluids, eat light food in adequate amounts and use over the counter medicines like Tylenol and antacids if required. Hope this is of help. Best wishes.
