Hi everyone..firstly thank you all so much for your responses to my post a few months ago. I have changed doctors and have reduced my dose of levo to 75mg and have felt sort of okay after the initially feeling rubbish. My question is I have been given a 25microgram tablet by a co called Wockhardt and a 50 by Actavis. I have never had these brands before and have had a really weird funny stomach since I started them and just feel a bit odd. Has anyone had this problem?
