Floating through space symptoms and conditions

I agree, for me this is a horrible drug! This is the 2nd time my allergist prescribed it to me (last time was this past summer and I had severe panic attacks and thought I was losing my mind) this resulted in me returning back to my GP and him putting me back on Paxil (which I had been off of for a year). I was extremely reluctant to use this again but thought i might be able to manage it this time (with the help of Paxil).

My allergist prescribed Prednisone to me 2 weeks ago (5mg 3x's day for 3 days then, 2 2x's day then 1 for 5 days) I made up until the last 3 pills. I had severe brain fog and felt like I was floating through space. I couldn't even remember driving to work and parking my car! Extremely fatigued (I have diabetes (which is under control, but I had to keep checking my bg because I thought my sugar was dropping to low). Now, within the last week of taking the Prednisone I have experienced aching in my kidneys and I think I have a kidney infection.

Can Prednisone do this to you??

I am calling the doctor tomorrow. Today is the first day without Prednisone and I feel like I am totally out of it - really spaced out, dizzy, panicky and a bit nausea.

How long does it take for you to get Prednisone out of your system?
