You may face some discomfort comming off them. They are stronger than the vikes but, how long were you off the vikes for? And, If you don't mind my asking, are you taking them as directed? If you are just taking them for a couple weeks it shoulden't be so bad. At least I hope not, for you. Good luck, let us know how it goes. Its a very good question that could help someone in the future. Stick around, there is alot of support around here. Cathy
I don't know anything about Dilaudid, sorry. Others should respond soon. It's early but they will be coming on soon.
