Lisinopril and sice

I have been taking Lisinopril since 7-24-07. Shortly after starting this med I began itching all over. It felt like bugs were biting me but I never saw any bugs and there were never any marks but I'm always itching. I attributed this to the hot muggy weather we've been having. I also need to sleep a lot. Several naps a day and almost all day on Sat. and Sun. I have had a head/neck ache on the lower left sice of my head which I thought might have been a side effect of a fall I had taken in June. A lot of constipation problems also. Now I am reading all the above side effects of this drug and I think this is my problem. I have not taken Lisinopril for two days now and the itching has stopped. I've also gained some weight but attributed that to the fact that I seem to be always hungary. Now I am really wondering. I have taken myself off this drug and will talk to my Dr. on the next visit. I think this website has been a miracle for me.
