migraine prevention
"Writing again, I guess amlodipine has something to do with my sleep stages. I feel some changes in the depth of night sleep. Before taking this med, I was generally having very deep and unconscious type night sleeps and regular migraines in the base of skull (occipital nerves) after awakening in the morning. Whenever I was very tired and feeling very sleepy before going to bed in the night, I woke up in the mid night due to severe pain in the base of the skull. Whenever I suddenly awaken from deep sleep due to external interruption, I found myself a bit confused for some time. With amlodipine, I have moderate depth of sleep and don't get confused if suddenly awaken / interrupted from sleep. No migraines so far."
