I'm so sorry to start yet another thread but I am very curious if this could be raising my blood sugar. About a month or so ago I started atenolol at 12.5 mgs and that is about when it started to rise. Three nights ago I started taking it at night at bedtime because I have a lot of early morning anxiety and thought this would help to be calm in the morning and it is helping. So three nights I took at bedtime and three mornings I woke up to higher then normal readings, first morning was 127, 117 and this morning 120. These are far far far from my normal morning readings, normally they were about 103 to 110 so now I'm wondering too if this med is what is raising my numbers through the day as well?
