When my doctors recommend that I take a new medication I look it up on the website Drugs.com to see possible side effects.
My rheumatologist gives me a paperbag of samples of meds to try when I leave her office without telling me any of the side effects that could happen. She's stated that I'm medication sensitive but these doctors can't know how each of us will react to a certain drug. I think they're just hoping one or more of these meds will help us.
Then there is I've heard that some doctors get kickbacks for prescribing certain drug company's medications. I don't know how true it is but here's a link to an article on the NY Times Website:
http://www.nytimes.com/2009/03/04/health/policy/04doctors.htmlGood luck to you. I'm glad you're going to be working part time and they know that you have fibro. I would recommend that you stretch each day, lift some light weights to keep your strength up, eat nutritiously to keep your energy level up, and lift your patients with good body mechanics. For the latter try not to be a hero and get help lifting a patient when you need to.
