I didn’t take it to counter the endorphin since endorphins are a great feeling I have been very intense in working out since my mid 40’s and have not stopped since. The sleeplessness began slowly in my mid 50’s despite my very active daily activities and exercise. I never suspected endorphins could affect the sleep pattern until someone mentioned that perhaps the reason I could fall asleep but not stay asleep was that I may have been working out too much. I did mention this to my family doctor but it was not taken seriously. I did not pursue the issue with my psychiatrist as he is fully aware of my exercising passion. I’m just looking for anyone who has successfully weened themself off of 0.5mg Clonazepam and if they took anything else to help the transition.
