Five weeks on from having pacemaker fitted for total heart block, taking bisoprolol 2.5mg once daily to control fast heart rates. I just cannot sleep, I lie awake every night for at least two hours before drifting off but only sleep for a few hours. Cardiac clinic suggested Valerian tablets might help but I am so scared to take anything that might affect my heart rate in any way as my pacemaker is working for 85 per cent of the time. I know it is anxiety keeping me awake but don't know what to do about it.
Any advice please friends.
