I just got my prescription filled of this medicine and now I'm scared to death to start it after reading all these comments ! I can't afford to be sick to my stomach all the time ! I had taken Adaptec now I'm wondering if I should just stick to that ? I'm 12 weeks post op of having knee replacement and still have to have pain meds sometimes now what is that going to do to me ? Why can't they make something with all these awful side affects especially when it cost so much and insurance won't cover it .So frustrating ...
