cluster headaches
"I've been on this medicine for about a week now. It helps me relax at night but doesn't make me sleepy like it makes others. I'm currently on 4mg at bedtime. I wake up with the same headache that turns into a migraine almost on a daily basis. My doctor said that it can take 6-8 weeks before the therapeutic dose starts working. I hope that's the truth and it does eventually start working. I'm desperate for a normal brain with no headaches or migraines."
