Unfortunately, all those side effects are very common with most BP medicines. If your BP is at stroke level, the simple fact that the medicine is working causes the dizziness. A sudden drop in your BP to normal levels causes all those side effects. They will get better as your body adjusts to a lower BP. It may take as long as 2 weeks for this to happen though. You might try a very low dose of 1 of those that worked wait a week or so to slowly increase the dose. That way your body can slowly adjust to gradual decreases in your BP. From a previous answer, Vasotec is in the same family as Altace lisinopril so it may have the same side effects. It is a good inexpensive choice. The others you have taken are all good 1st line choices. They actually have some of the better side effect profiles compared with other BP medicines. Good luck.
