My last flare I took 40mgs for 3 weeks recduced to 30mgs for one week then reduced by 5mg's per week altho if I felt things were getting a bit ropey I would hold at a dose for 2 weeks.
The more I flare the steroids seem to be less effective but at the moment they still work. Hope you are better soon, I have breastfed a baby when well and found it hard cannot even imangine doing it when flaring.
