sorry to hear about your insomnia and headaches :-(

if you're taking meds for your headaches (excedrin works well), make sure to take them as soon as the headache starts. otherwise the pain in your head can make it difficult for your stomach to absorb the medication. one weird remedy that works for me is ice-packs. i actually have an ice-pack hat that i use! it looks dumb but it works.

i hope you feel better.
