high blood pressure
"I've been taking Hydrochlorothiazide for six months.   I started out taking it with breakfast, but noticed it makes me a little sleepy and droopy.  I switched to taking it at bedtime, and noticed I slept better.  However, when I told my doctor this, he told me to take it in the morning because it will make you excrete excess fluid.  I switched back, and have the same results.   I've noticed only a slight drop in my blood pressure. That might be because I'm struggling to eat a healthy diet.  I have good days and bad days."
