Congrats on day 19...you have truly inspired me this morning. Thank you!
Sounds like you're doing great. I never knew how easily you can become dependent on these things either. I took it as prescribed and even brought up addiction/dependence and was told to not worry about it!! I did my own taper because I didn't like taking things and was concerned about how much they had me on. It was one of the hardest things I ever did and I didn't have to worry about addiction, just physical dependence.
Since you're allergic to ibuprofen, can you take something like Aleve? I believe that's Naproxin. I know a lot of people like it because you don't have to take as much. That may help with the aches and pains. Do you take Melatonin or Alteril to help with sleep? I find Alteril works really well for me. Have you checked out the Thomas Recipe? It has suggestions for things that help with the withdrawals. If you haven't, you may find some things that will help some of your symptoms.
Are you going to AA/NA or do you have some type of aftercare in place? It seems the people that have aftercare do much better than those who go it alone.
Congratulations of tapering so well. Keep it up. It sounds like you're definitely mentally ready to put all this behind you!
