A fib every time around 5pm

I have a pattern of when I get my AF but mine tends to be in the middle of the night  -1am or 5am is the favourite.     My other bizarre time is after a medical procedure or scan or similar and then I go to eat and bingo  - off it goes. 

Just because of a different pattern I have picked up in myself over the last couple of days ...I had a procedure on Wednesday and since them I have found that I am ready to take my evening dose of tablets a couple of hours early around 5 instead of 7 so I wonder if the dose you are on is so finely tuned your body is ready for the next dose?   Just an idea.  Would definately go back to consultant and mention more AF on  Coreg.   No experience of it myself.    

Firstly I didn't have Afib until I started taking BP meds.

I found that the timing of my Afib episodes was linked to the time a took my BP med ( Ramipril then Candesartan). I took them in the morning and found that an episode would start within 2/3 hours. I moved my BP meds time forward 6 hours and found again the episodes moved by the same time. I'm now on Bisoprolol which gives me fewer episodes and I've been taking in the morning and when I got an episode it was always around 3am. I've again moved the timing by 6 hours and so far no episodes at all, but my trial is still running.

I also had problems with Bisoporol when I was taking them in the morning until I spoke to the Pharmacist who recommended I take them in the evening about 9pm she said as long as you take them in a 24hr period when is irrelevant since then I have had no problems.

On another note has anyone experienced swollen finger tips and feet with any of their meds, also after growing really quick for a while my finger and toe nails have completely stopped growing haven't had to manicure either for at least 8 weeks, but my fingertips are swollen look a bit like ET.
