Well, she did give some vague advice about dropping to every other day for a week or so...

I've done some reading and looks like a reasonable approach would be to do that for a few days ... then maybe do 1/2 tablet (10mg) for a few more days then stop for a couple days before starting with the sertraline. Although there is some people that suggest that because both tablets are short-life SSRI's then a rapid changeover might be possible given they both have similar methods

Basically given the tablet has a 1/2 life of 36 hours then weaning off over a period of 5 1/2 lives seems the accepted approach.
