I cant comment on this particular medication, but there are lots of options and it may take sometime to find what really suits you.
Just keep positive and keep your chin up. There will be a combination that suits you, but it may not be the first option. Dont lose the faith - keep fighting and remain positive.
I was diagnosed over 10 years ago when i was 43 and I am still working full time, living a full life and managing a family home. I get tired and frustrated with the symptoms, but they are manageable.
If Rasagiline doesnt work something else will.
Wishing you all the best
