You can do it. You're right, it won't be an easy ride, but it is most certainly doable. You aren't alone either. There are many, many others going through tram withdrawal right now. You should look for a member by the name of Emily Post and read her journal postings. It's because of her that I am nearly 300 days free from tramadol.
Hopefully this will actually show up...if not, just look for Emily's profile and her journals and you'll find many others in the same situation that you are in.

Stay strong and do not go get that refill. You can do it!
