just to be clear.
you were taking 300mg of 25/100 daily?
then the doctor switched you to four 50/200 CR plus 1.5 tablets of 25/100?

300mg is a very low dose. when were you diagnosed, how old are you and what other drugs are you taking may i ask?

are you seeing a neurologist?

just from my experience with CR, there are i believe 2 generics, i take the one made by MYLAN, i think the other generic was much less effective but i could be wrong. but that might be something you can discuss with your DR., trying another generic or increasing the dose to 1.5 CR'S as a test. normally you start with a regime and modify it as needed.

i'm not a doctor. be careful.
