I have been taking Hydrocholorthizide and I love it... I have had untreated high blood pressure for 7 years and could not wake up from a nap without a killer migraine headache ...until now thanks to the Hydrochlorothiazide, I feel normal again. The best part is I would FLIP OUT almost to the point of rage over the littlest things before--- and now Im calm, fine! Just got prescribed Hydrochlorothiazide-Lisinopril and Im nervous about the side effects that may or may not occur... will keep you posted.
