Side effects: serious tiredness/fatigue/lack of motivation when starting or upping dose
Blood pressure dropped for a couple of weeks from being a bit high, which gave me occasional higher heart rate when going up stairs etc - then stabilised at 'perfect' after a couple of weeks
Sleeping much better - 8/9 hours a night; lack of stress, very chilled out - these are positive side effects
Would I take it if my condition was mild and occasional? My condition was like that at first and i didn't - i wish I had! But I had no diagnosis then and probably wouldn't have gone for it if I hadn't really needed to - but it has helped me A LOT. I feel more normal most of the time and just can do normal stuff again that was impossible before.
If the condition is limiting your life - try it. Give it a few weeks. It was S bit weird st first but never unpleasant.
Good luck with whatever you try!
