So I am also on penicillin rn for the tooth thing (on the last day thank goodness)... while I appreciate the effectiveness of antibiotics, and is one of the few pharmaceuticals I actually think is of benefit to humanity.. I however DO NOT like the other effects that any antibiotics do to me personally, it really messes up my cardiovascular system and heart regulation which scares me sometimes because it is far from unnoticed.
P.S. - Merinol sucks haha - u ever tried it? I did nothing when I did years ago.
