Thought I was the only one that could go to sleep without medication and two hours later, awake for the remainder of the night. For thirty years I took 2 generic benadryl at midnight when I would wake up. That process would work sometimes and sometimes not. It was not unusual for me to go to work at 2 or 3 am. Several times I tried to wean from the generic benadryl, without success. I followed all of the recommendations for a good nights sleep, exercise, dinner early, no alcohol or liquids at night, dark cool bedroom, no tv in bedroom, sound machine, regular routine without success. Six months ago, had a knee replacement and did not sleep for a second for two weeks, even with narcotics. Surgeon sent me to a sleep doctor, who had me do an in home sleep test. Results were 51 apneas per hour, and he said that any number over 30 per hour is considered severe. He prescribed CPAP and found out very quickly that the silicone mask caused open sores. Tried two other masks, same issue. My SleepMed therapist was no help. I started searching and found liners for ResMed P10 nasal pillows, which corrected the problem. But, the CPAP did not improve my sleeping, so back to the sleep doctor. He said I had two problems, Sleep Apnea and Insomnia and the only solution for the Insomnia was medication. Now, I take Melatonin when I go to bed and two hours later Clonazepam which works for another 3-4 hours. The Sleep Doctor said do not take the generic benadryl. Good Luck to everyone with a double whammy like me. BJ
