I do not have a lot of information on this drug. What I wanted to say to you is:
Do exactly what you are doing. Continue to research the drug, get opinions and testimonials for others who have taken the drug, learn as much as you can about it, insist that your doctor explain to you why it is beneficial to you, and then make your own decision about taking it or replacing it with another similar drug, or discontinuing its use.
Just make sure that your decision is one based upon fact gathering, informed information, and your own personal health needs.
Hopefully someone will be along who has experience with the drug and who can share their information with you.
Peace and Blessings
Look For The Good and Praise It!
