I've been on prednisone for about 10 months, with a small 1 month break around June. So more like 9 months. Every time I dip into the 20's I start to flare again, Bad. The Doctor wans me to try a lactose free diet and keep tapering. I'm getting worse by the day as I'm at 20 mg starting tomorrow. My point to this all is My life spirals out of control if I go below 30 mg. then It always takes about 3 weeks on 40 mg to normalize myself again. The Doctor says I have to get off pred soon but nothing is working.
