I've been on pred so long, I can't really remember... hmm... anyway, I was at 10 a day initially, but have gone up & down, with weeks of 60+ not uncommon, with the "ween" process afterwards. I was on 15mg lately, but we're trying to get me down to 5 a day. It's tough. There's a big difference between 15 & 10 and between 10 & 5. I'm "officially" diabetic now, and pred can *really* throw the blood sugar off.
