Not to open a can of worms, babbsjoy, but you may be able to change plans again. If you have a Medicare Advantage plan you can switch plans from 1/1 to 3/31. If you have some other kind of plan there may be an 'escape clause' that allows you to drop your new plan for a new new plan, and what njx58 described about you already being on the Tymlos might qualify you to do so. A lot of hassle, yes, but there are a lot of plans out there and there's probably one to suit you better.
