Fairysue--
Should you switch to another drug? That didn't really work for me. I just got dependent on another one but, my thinking at the time was not too clear. That pain you feel when you don't take the meds or when you wake up is your body crying out from every cell for the pill.
I tried to wean myself off the stuff and a slow approach seemed logical, but it didn't work for me because it was too slow. So, in a moment of stunning stupidity, I tried to get off cold turkey by just quitting. What a mistake that was!
I was hurting and sick and could not even get out of bed for an entire month. It started to get a little better where I could keep food down (I lost 35 pounds in two months) and my doctor suggested methadone to help me. By that time, I was over the worst part, but it took a full three months before the drugs were out of my system.
My wife works but she was the reason I made it through everything because I'm basically a coward. I have had a lot of pain during my life, so that was not as difficult as the tireness and nausea I felt. I'm sorry your marriage is not as strong as it was, but I understand now how much my wife loved me after what I put her through. Believe me, you will be a different person when you are off the meds.
If you need other help, try to explain your situation to a doctor you trust. I found that once I outed myself and told my doctor all I was dealing with, she had a plan to fight it. I was the one who deviated from her plan, so I would advise you to start slow and decrease your dosages. Show some patience, don't do what I did.
My doctor also prescribed me two antidepressants, Cymbalta and Wellbutrin, along with Lyrica, a non-addictive nerve/pain reliever and all of those kept me sane. You already know the task ahead of you and you're smart enough to know it won't be easy. I'm encouraged that you've got the confidence in your own strength to do this.
Please keep me informed about your progress and I'll be here if you need to talk. Just send me a private message.
