Wolfstarr, Doc is correct there are new types. However, a doctor might only neet to up the dose. You didn't mention and I forgot what you're taking. Whatever you're taking go to their web site. They will tell you the ceiling for that medication, and then you can see if a large dose is available. Many of the medications I've been on before they've walked me up the scale until they for the correct millagrams for me. I wouldn't be surprised if your's also had a higher avaiable dose. The trick of course is that sometimes circumstances will give the apperance that our Meds are not working. This is where the doctor comes in. Hey Wolf, we're not getting any youger and after 20 years we could very well change chemically as well as physically. Don W
