Yes, that's what I'm saying but not being a doctor can only cite my own experience and what I have read of others' and researching sources online.
As Annie says, sometimes you can get worse initially with pred or if the dose is too high and there are lots of references to this tho it didn't happen to me.

The following is a paragraph from an article at this link:

http://www.australianprescriber.com/...e/30/6/156/60/

"Prednisone

Prednisone or another corticosteroid is the primary immunosuppressant used in myasthenia gravis. Sustained improvement or remission can be achieved while patients remain on treatment. A typical course for generalised myasthenia gravis would use 1 mg/kg prednisone daily (0.5 mg/kg for ocular myasthenia gravis) until clinical control is achieved and then weaning either directly or by initial conversion to alternate daily dosage, with the determination of a maintenance dose by trial and error during a slow withdrawal of medication over many months. Deterioration in myasthenia gravis can occur in the first few weeks of treatment so the dose is often increased slowly. The mean time to maximal effect of prednisone in myasthenia gravis is six months - much longer than most expect."

All the best

Draggin',

Annie is right, everyone is affected differently. I started at 5mg in September, for a few days I was a little weak, but after around a week I could tell a difference in strength. I was really bad off when he prescribed it, he asked me at the appointment after all the strength tests how I got into his office. Since then he upped me 5mg every week to my current 20mg dose. After every dose increase I could tell difference. I hope your 12 days on it work well for you, and hope you become stronger, and stronger each day.

Warm Regards!

Thanks all....I did speak to my Dr. He said to give it time sooo......he also told me he has seen this 12 day thing work for MG exacerbations as well as in MS. Guess Ill give it the full 12 days and see. I just dont want to go on it daily ....Ive read that too many regret it later. Thanks again to all that posted, Draggin'
