I take 50 mg of Metoprolol twice daily and a 5/20 mg Lotrel once daily for high blood pressure, which has been consistently under control. I also take .5 mg of Clonazepam twice daily for Panic Disorder. My sleep is horrible. I wake up every night, usually about 2 or 3 a.m. and usually a couple of times between that time and about 7 a.m. Even while I am sleeping, it is never restful sleep. I have very vivid, strange dreams all night long. Not really nightmares, but just strange, sometimes unsettling. I have read that Metoprolol can cause this type of thing, but when I asked my GP about it, he said it was more likely the Clonazepam (a form of benzodiazepine). I think my GP is wrong. I think it is either the Metoprolol or maybe panic symptoms during the night (sometimes I wake up with my heart racing). Either way, these unrestful sleep patterns are starting to get to me. Any ideas? Thanks.
