I just caught on to a pattern, that on heavy workout days I have trouble sleeping that night. Not always, but most of the time. Then I realized that pain may be keeping me awake. See, after a hard session early in the day - that evening my body just aches! This seems to be keeping me awake. So, I'm thinking maybe some natural painkillers (herbal?) might be a healthy way to reduce this pain and help me sleep. Maybe something like Bromelain? I don't know much about these things and have no experience with them.
I think an epsom bath and light massage would help out a good deal, but I'm wondering if there is anything I can supplement to reduce the pain without drugs.
