I missed a dose of metaprolol one day because I was out of the medicine. I nearly passed out in the shower when I held my breath to rinse my hair. I have forgotten to take it a time or two in the past. I always feel like crap if I don’t take it like I should. That is scary stuff.
I take atenolol, but sometimes I forget to take it on weekends.
It doesn’t seem to make much of a difference..............
