My rheumy makes me go very slowly, 1 mg a month.
So for example if I was on 5mg (like I am am at the moment) this would be how I'd do it:
Month one - 5mg a day
Month two - 5mg one day, 4 mg the next day, 5mg the next day, 4mg the next day - etc for the rest of the month
Month three - 4mg a day
Month four - 4mg one day, 3mg the next day, 4mg the next day, 3mg the next day - etc for the rest of the month
Month five - 3mg a day, etc etc
I don't know why I do it so slowly - maybe because I am on a low dose to start with and keep having trouble getting below 3mg a day?
