Insomnia: Insomnia can be very disturbing. It's not clear from your post, however, what caused it. Was there any damage done during the procedure, or it was pure stress related thing. I would suggest you discuss your situation with a doc in a face to face environment to grab a better understanding of what's going on and how it can be remedied.

Discuss cause: It is best formgountomtrulynunderstand the cause of your sleep disturbance. In the meantime, proper diet, exercise, as well as meditation or self hypnosis may be beneficial in easing you off to sleep. Tryptophan and melatonin have mixed results in patients using them for sleep.
