Yes, welcome indeed. I've been on Betaseron for 14 years or so, so can offer some help with that. The decisions can be overwhelming. The good news of course is that there are now meds that might help -- back 24 years ago when I was diagnosed there was nothing!,
and you can always switch meds if one doesn't seem to work out for you. Usually a doctor likes a patient to keep on one med for 9 months to a year before switching, but there is still that option.
Don't hesitate to come back with more questions..
