insomnia
"Here is my problem with Belsomra. I am a 50 year old male - 6' 2'' 190lbs. I am currently prescribed the 20mg dosage and it seems to work okay some of the time. By accident I doubled dosed one evening - 40mg - and had the best sleep of my life. Woke up refreshed after eight hours of sleep and had great energy and alertness the entire day. I feel I need a higher dosage for it to work for me."
