Comparing Carvedilol

For High Blood Pressure This medicine gave me headaches and doctor said it did not work to lower my blood pressure. At the office I am 125/100. At home, I am usually 120/80 or lower. Can this be white coat syndrome? Anyway doctor is switching me to another medicine. This next medicine will be my 6th blood pressure medicine.

For High Blood Pressure I've been on carvedilol for 6 months, in conjunction with lisinopril, and it has worked well on lowering my blood pressure, where the lisinopril alone was barely fazing it. With no medicines my pressure was running around 200s/120s, on lisinopril alone it was only coming down to 180s/100s. Since being on carvedilol, it runs (in my opinion) a almost too low, around 90s to low 100s over 50s. This doesn't bother me so much, but occasionally, and for no reason I determine, it will either spike or plummet. It has been as high as 180/98 and as low as 86/38. THAT was scary. I also have nausea, dizziness upon standing or moving very suddenly, and nearly disabling headaches. I like what it does for my blood pressure, but not how it makes me feel.
