... week. I've been having some serious symptoms, not so sure if it's from the Medication or something else. Nausea, etc.. but I've been having episodes of extreme muscle weakness and limp legs. To the point where I fall or grab on to somebody. Dr ordered blood work and doesn't seem to think it's from the medication. I've also had the tingling in my hands. I just don't know if it's worth it?? I lost 10lbs the first month, which is good. I'm just wondering how many have actually had the serious/severe effects. Maybe some of it is in my head? I dunno know. :) Thanks
