Thank you so much for the information. I'm still fighting this cold for 2 weeks now.. The prednisone is working very well tho, haven't had a flare or any pain since starting it.. Once I feel better I'll head over to buy the multivitamins that was suggested.. Can I ask something, the vitamins, is it better to get the different type of vitamins that was named, or just buy one bottle of multivitamin and that should work?? My doctor said I can start taking vitamin if I want.. So what do you guys do, buy multi, or separate different kinds of vitamins? Ty
