Medrol

I have been on Medrol since November 2011. For a while, I needed 6 mg daily. For the past year, I have taken 4 mg daily. I have tried to wean off it several times, unsuccessfully.

I took my usual dose the day before yesterday, so 48 hours ago. I then decided to start taking Medrol at night instead, after reading an article where a doctor recommended taking it at night to wake up with optimal cortisol levels. So the plan was to take it last night before going to bed.

However, I did not feel sluggish at all, so I decided not to take anything. I expected to feel sluggish with almost flu-like symptoms this morning, as I always do when trying to wean off Medrol.

But it's been 48 hours, even a little more, and I don't feel bad.

So now my question is: should I go back on Medrol anyway (that is, take it tonight before going to bed), or should I simply wait and see what happens?

My doctor seems to think I will need to be on Medrol for the rest of my life for adrenal fatigue. When I last saw her, in September, she prescribed enough Medrol to last me a whole year (I see her once a year).

It seems strange to me that I would all of a sudden be able to stop taking Medrol, without even having to wean off it slowly, after failing so many times before. But the fact remains: since going on Medrol, over four years ago, I have never been able to go even 24 hours without it. Now, it's been more than 48 hours, and I still feel OK.

Has anyone else experienced anything similar?
