Thank you for your replys. Yes my dad has very low blood pressure. He has had so much dizziness that he was always bending down to the ground and holding on to something. Kind of like he was so dizzy he was going to fall off the face of the earth. Now, with this combo of meds he is not dizzy anymore. This is the first time in years that he says he is not dizzy all the time. To me that was the main concern to get the dizziness under control. That was such a miserable symptom. My mom complained because they could not go anywhere because of the dizziness. Now, he can go some places but is so out of it he can't talk to people and keep up with what is going on at all. He is so dependent on my mom he has become her infant and he freaks when she is not with him. She is loosing it because she needs a break from him sometimes. How do we deal with this? Any ideas would be helpful. Thanks.
