Well, the best way to take it, from personal experience, is to spread it out through the day. When they come in 6 day packets, they start with 6, and reduce by one each day, until you have taken your last pill on the 6th day.
If your doctor has recommended 30 mg a day, then remember, when your condition gets better, slowly reduce the amount of Prednisone, for about a week, until you are down to about 5 mg.
The reason is that, if you stop suddenly, your body may react in a very bad way. The body quickly becomes addicted to steroids, and you will likely be in a lot of pain if you stop suddenly.
Hope this will be of help. Take care now, and take it easy on the steroids.
