Boyfriend prescribed these for chronic cluster headaches. He's been on a cocktail of drugs / injections / nerve blockers (can list of anyone wants to know!!). It's day 7 of topiromate he is sooooo spaced out its unreal. Does it settle down? Touch wood, after years of sometimes up to 5 clusters a day he hasn't had a headache in almost a week! But I'm so worried about him. His energy levels are so low (I think from the chronic pain, fatigue from never getting a decent sleep, trying to hold it together to work etc etc). Is there anything he could do / eat / take to help with the fatigue? Any advice would be so gladly welcomed.
