Hi. I'm on 6 x 5mg for a week, then reduce by 1 each week. I also don't know the best time of day to take them or whether to take them all together?
Ok, so, 30mg a day and reducing by 5mg each week, 6 week course. Yeah, that will be horrible on the bg levels. I can't advise on whether or not to take them, but it is generally not a good idea to suddenly stop taking them while on a high dose.
I take 7mg everyday, but it's part of being a transplant recipient and there is no way around it. I have heard of doubling and tripling insulin while on pred, but you really need to get a hold of someone to get those levels down. I don't know anything about your condition that your doctor is using pred to treat, but I'd be looking for as much info on it as possible to see if there are alternatives to pred.
