Broken hearted symptoms and conditions

Here I sit broken hearted as my side effects begin. Today is day 5 on Lisinopril and have not been able to sleep at nigh due to dry cough which began the same day I started the med. I was taking Tiazac and my BP was a little high on the low number (90) so I was switched to this Lisinopril HCTZ 20/12.5 and immediately began to develop cough, light headedness, headaches, blurry vision etc.. The bad thing in all of this is that I'm a diabled Vet and the VA put me on this medication about 2 years ago and I began to develop sharp pains in my head in the exact same spot everytime - I went to another other DR and told them about the pain and she sent me for a brain scan and I also showed her the medication the VA had prescribed and she said STOP taking it. So now I find out that I'm taking it again and the sysmptoms are back -- I guess I could stop smoking, drinking beer, no more cofffee or pepsi and stop eating sodium etc. I probably wouldn't need any drugs????????
