My husband is taking 2 drugs to control high blood pressure. He does not sleep well and I m wondering if either of these drugs could cause restless sleeping. He is taking amlodipine besylate 5 mg and Losartan/HCTZ 100/12.5 mg tablets and a baby aspirin each day. He had a slight stroke in 2009 at the age of 51. His blood pressure yesterday was 132/80.
