PredniSONE and weird sensation

I was diagnosed with a quirky little disease called "Minimal Change Disease" - my kidneys decided that my body did not need any protein, and without any protein in my system, I gained 55 pounds of water weight, along with few other nasty side effects like having cholesterol in the 800's and blood clots in my lungs. At this point, I have been on the drug for a little over three months - 70 mgs for the first 6 weeks, the point at which the disease went into remission. The last 6 weeks, I've been tapering off - and will be off Prednisone by the end of this week. Ironicly, I had been taking a drug that causes water retention to fight a disease that causes water retension. Fortunately, after losing the 50 pound of water weight in less than three days, I didn't see any of the massive weight gain some have reported. I have gained about 8 pounds in the past 6 weeks that I've been tapering off the drug. The only other side effect I had was this euphoric, ethereal feeling I would have about mid-morning where my concentration was that of a 2 year old (I have experience in that because I have a 2 year old), and by mid-afternoon, I would race around the office in a flurry of activity - and get absolutely nothing accomplished. It was a weird sensation - kind of fun, but disconcerting - of being giddy as though I was drunk. I had to really sit down at my desk and force myself to behave and do my work. I also had quite a few nights in which I would wake up in the wee hours of the morning and to force myself to read the dictionary just to fall back asleep. Sure the drug has some nasty side-effects, and can really mess with your head, but so can being a 200 pound albino blueberry. And there were no Oompa Loompas around to take me down to the juicer. As to the side effects, I realized that the euphoria wasn't permanent, and I had to have a bit of fun with it when I could, and as to the weight gain, five pounds is nothing - though, there is much in my closet right now that I can't wear.
