My post was a little confusing on the time period- I was at around 4mg after a year and then several attempts before I got to 2 mg after the 2nd year. I don't try if I am travelling or have other health issues happening because I don't want to confuse symptoms (eg I fractured my spine 3 months ago - so didn't want to try and reduce Prednisone while I was dealing with that). I find that when I start to experience side effects from withdrawal, it takes 6-8 weeks of increasing the dosage back to previous level before I feel back to normal. This time I am only experiencing fatigue - not pain, so I am optimistic.
