I definitely do not plan to go off SSDI entirely. Also, because BOTOX is so effective for my migraines and costs a lot of money ($12K a year without insurance), Medicare is so important for me (for other things as well, including psych treatment). And even on BOTOX I get migraine attacks which I abort with Sumatriptans and refrigerated suppositories Indocin and Promethazine, all very expensive, so without Medicare I would not be able to afford healthcare.

I did not know that Medicare is for life. Thanks so much to all of you. I will go to the local office - it is actually within a walking distance from where I live - and ask the questions.
