Swaying is not a typical effect with either drug, but dizziness can occur with both of them, and low bloood pressure and faintness with bromocriptine; but bromocriptine seems the more likely cause.A way of trying to find out which seems to be responsible for the effect would be to delay taking first Diclomol for a few hours in the morning, and then on a different day delay taking bromocriptine until mid-morning. If the swaying is due to bromocriptine then it should not occur on getting up before your uncle has taken it.
