New Insomnia Challenge?

Has anyone been dealing with insomnia recently?  Within the last month I have started to get random insomnia at least once a week and it has been interfering with my school performance so I am worried  :s

I had really bad sleeping problems, I woke up at 4 am every day and couldn't fall asleep again.  I think this is quite common when having an eating disorder, but it will go away when you start eating "normal" for a long period of time and have a healthier weight again.
