I found out by accident that tramadol significantly improves my restless leg syndrome. I take 50mg twice a day...once after lunch another 2-3 hrs before bed. I used to get excessively tired mid day with uncontrollable yawning and my RLS would go off the charts. I noticed that if I took the 50mg tramadol mid day BEFORE these symptoms, they would not occur. So not that tramadol gives me energy per se, but it prevents a horrible energy crash and a terrible onset of RLS symptoms. When I first began using tramadol 10 years ago or more, I did notice that when i would take my earlier dose (usually to prevent symptoms while flying), I would be in more pleasant mental state, prompting me to refer to it as my happy pill early on. That aspect has subsided or is much less noticeable.
