I hate this medicine. I was prescribed a Z-Pack (azithromycin) by my Doc a couple days ago. Got very little sleep the first night; got no sleep at all last night. Heart racing, itching, feeling like I wanted to jump out of my skin. When I got up to go to the bathroom at 3 AM, the lights seemed to be pulsating and strobing. That was the final straw. Called my Doc today and told his nurse I can't handle this medicine and am taking myself off it. I hope I get some sleep tonight - but I won't be surprised if it takes several days to get this poison out of my system. Never again with the Z-Pack.
