How long can I take prednisolone tablets before it effects me in a bad way? - prednisolone more drug_warnings_recalls

I have emphysema and I think if I will take my tablet prednisolone breathing a little easier and I eat better (my appetite is poor). I do not know why this is happening, but my doctor has said that this is not a good idea to continue to. How many mg can be taken and how long until it starts to hurt.
