Taper

Down to 15mg. I feel like the hot flushes and anxiety is getting worse

From 100mg for 3 days then 50, 30, 20, 15 each week

I've never been on pred, but I do know there is an alternating tapering method that could ease the symptoms and be easier on your adrenal glands to adjust.
You could try going back up to 20 one day, 15 the next, 20, 15, 20, 15...15, 15, 15...etc. Discuss it with your doctor rather than fully suffering.
When you get down to the lower dosages, the drops will be a much greater percentage, so this could work well for you. And yes, I learned it here as well as from friends who were on it.

Thanks everyone. The anxiety is horrible. The hot flushes set me on fire. I feel like I’m in menopause. Atleast im getting more sleep so I’m obviously losing some of the energy it gives.
