Lisinopril and night mare

I am 23 and had a blood pressure of 160/101. I took this medicine for one week and during that week developed a night mare of a dry cough. It has been horrible!!! I went back to the doctor and he took me off and prescribed me a new bp medicine that I have not taken yet. I haven't taken lisinopril for about 3 days now and the cough is still taking over my life. I'm not going bowling with my friends tonight because I am so exhausted from the cough. One night, I coughed so violently in bed, I vomited all over myself. It was disgusting and embarrassing. It has been hell and I hope it doesn't take much longer for it to go away. Does anyone have any guesses or experience with the time it takes for this cough to subside?

The fitfth day on Lisnopril, after a good night's sleep, I became so sleepy about an hour after breakfast, couldn't keep my eyes open. (Took a half hour nap).

Early evening I became dizzy, chest pain, I thought I was going to pass out. (I was out for a social evening of cards)

Next day, I took 1/2 the dosage....I seemed to be okay.

Five days later, I started sweating, chest pain, pressure dropped very low. I stopped taking Lisinopril, still don't feel up to par.

I was on Univasc, that worked well for me, however, the new Medicare Drug program didn't pay for the drug and my doctor didn't want to spend time to ask my insurance to make Univasc a "preferrred" drug for me and so he prescribed Lisinopril...WHAT A NIGHT MARE!!! .

I will be seeking another professional opinion!
