I didn't have high blood pressure. But the glucose test really isn't that bad, there is a crap ton of sugar in it obviously lol so personally it made me nauseous after i had drank the whole bottle. It tastes like diluted flat soda of whatever flavor they give you (orange,fruit punch, i think lemon lime is one.) For me it also kind of burned as it went down and gives a not so great after taste. But it's honestly not as bad as you might think it is.
