I have been taking this for 8 months roughly, slow release 80mg one tablet per day.
No real side effects and has stopped my palpitations and lowered my bold pressure.
However I have been off work for those 8 months so have been able to have as much sleep as I need.
Went back to work yesterday (9-5) office job and it was okay, but instead of my usual ten hours I only got about 7 and this morning i felt beyond exhausted and a bit breathless while trying to get ready for work.
Does anyone else feel they need more sleep with these or ever felt breathless? My Blood pressure was high also as it was only half hour after taking my tablet and it only feels high in the morning before I take my next one, heart rate is always higher then too!
