I took methylprednisolone in the six day dose pak when I went to the ENT physician in May, after my hearing loss. It was like a miracle drug for me. As I have arthritis, I thought I had not felt this well since my 20's! It seemed to cure all my ills, so to speak. I also lost 7 pounds within five days (probably due to all the fluid I retain). I did not put the weight back on, either. I felt like I was on speed. I was full of energy. I cleaned for two days straight!
There was, however, a down side in my case. I had increased blood pressure, increased heart rate, red flushed face, and increased blood sugar. It seemed to correlate with taking another drug of Prilosec. It only happened two days of the days I took it and it was on the days I was taking the Prilosec. I actually had to go to the ER. They told me it was common with this drug and I could "either take it or not take it". I decided to continue to take it but I lowered the dosage to less than what they had for each day and tapered down with less pills per day. I finished the pak in 8 ot 9 days, versus the six days. I did feel really bad for a day after finishing the medicine, but only for a day. For me, I had aching all in my legs, but it could be due to my arthritis.
I feel fine after taking the drug and it actually helped me feel physically well for a while. If it were me, I would want to take the drug, as it is not a long term dose you will be taking.
Good luck, Tumbleweed. I wish you the best in a speedy recovery!
