I have been on Metropolol 25mg twice a day for a little over the last year. However over the last month, I've noticed that the morning dose seems to be coming up short. About three to four hours before the evening dose, I begin to get a lot of palpitations. Way more than usual. Sometimes they seem to come in series lasting longer than a couple of seconds. I keep expecting to trip into AF at any time.
If I wait and take my evening dose, about a hour after that the palpitations basically stop and I can get to sleep.
So my question is... have people found that over time the dosage needs to be increased?
