Have been taking Toprol XL since about June 2007. About three weeks ago suddenly developed insomnia. Went to my Doctor this past Thursday and told him about insomnia problem and asked if it could be connected to Toprol XL. He said he was unaware of insomnia problems with Toprol but that I should cut dosage in half from 100 mg to 50 mg per day as I had not had any problems at 50 mg per day. My blood pressure has also shot up this past three to four day after being low at the start of the week. My doctor prescribed Ambien for the insomnia problem Slept okay the first night obn ambien but did not sleep well last night. I just want to get back to normal. So, I am going to stay on top of doctor to get over the terrible insomnia problem.
