First, please try not to compare your experience with others. What you are going through is YOUR experience and yours alone.
Since you are now down to a half Tram per day...25mgs, I would bite the bullet and just stop. The does you're on is very small, and to start taking Vics to make yourself feel better, albeit, a short time, you are only putting off the inevitable.
What you Can do to help yourself, is tell your dr what you're doing, then ask him for an rx for Clonidine. This is a blood pressure med, but also used to help people through withdrawal. It really works great! Cuts down the sweats, the restless legs, and so on. And if it doesn't help the pain in your legs, Hylands has a number of product out geared totally towards that reason. Many people have sworn by it.
So step one...talk to your dr. Be honest, that the best way to go. Use the Clonidine, they hylands, a small bit of aspirin or Ibuprofen for the aches, take plenty of vitamins, force yourself to eat, but most importantly, drink LOT'S of water. At least 4 bottles a day to help flush your system out.
And last but not least, begin an exercise regimen. Get walking. Even if you only make it a few houses down at first, consider that a victory. Slowly you will find yourself able to go further and further before you know it. I know your legs with hurt, but exercise is the best thing for that. I use a walking stick sometimes myself. I used one of our 'alarms' we use in our windows. He put a rubber end on one end of it, and it's really helped. If I get to walking and no longer I feel I need it, I just carry it home.
Again, you are on a low dose. Please don't trade one addiction for another, that's never a good idea. If you were taking tons of Trams, I might say 'maybe', but one a day, honey?... you can do this!
And one more thing. Because it sounds so scary, people try to do every thing they can to avoid withdrawal. This is a myth, and simply not possible. You've only been taking ONE a day, so try not to be too afraid, but just jump in and do it! Take your last one, and tell yourself that that is over!!
From reading your post, it sounds like you're ready. I wish you the best. I have no doubt in my mind you can do this. Before you know it, days are going to go by, and you will feel better and better each day.
