I know appetite loss and cognitive effects are common with migraine, and I'm learning that insomnia is a factor for me too. It's driving me crazy in the middle of my current cluster (at minimum every other day since 4/13). Because I'm spending *so much* time somewhere in the range of prodrome to migraine to postdrome, I feel like it's a rare good day when I can focus well and consistently or get to bed at a vaguely reasonable hour. And I tend to under-eat when stressed, as well as having very specific foods that I can stomach when I'm in somewhere in the migraine process, which means I'm having trouble getting adequate nutrition. I've received a lot of the standard advice about sleep hygiene with variable success--that one's sort of an ongoing battle. Anyone have any survival tips for appetite suppression and cognitive issues?
