I Had A Craniotomy June 1st And Was Home By

I had a craniotomy June 1st and was home by Friday-had Dexadron and off of it since June 13-was having insomnia on it but now a week later I do not sleep-have not had coffee or tea on herbal teas and water. May sleep 1 hour or 15 minutes but no more-I go for walks every day and even twice. Have rest quiet periods often for an hour or 2 with eyes shut in a somber room but no sleep. Although I am in good spirits I do not want to get exhausted since I'll be having Chemo and Radio therapies.
