Dare I get on my varicocele soapbox? If you are a middle aged man and suffering from insomnia and low t make sure you don't have a varicocele. While completely subjective and based entirely on my own personal experience, within 1 week of having my varicocele repaired i was sleeping through the night and haven't had a bad nights sleep since. Coincidence? Who knows, but worth ruling out in my opinion since they are fairly common in men and another area where conventional medicine doesn't get involved unless you have a disease or fertility issue.
