Benazepril-hydrochlorothiazide

I was recently taken off of 10mg of Lisinipril and put on 20mg/25mg of Benazepril/HCTZ. Is this medication the same as Lisinipril?

I am also noticing that my heart does weird flips. Is this a side affect and is it something to be concerned about?

I was also taking Seroquel and stopped a month ago. This is when I noticed that my bp has increased to 144/92 from being 120/75. I am having trouble sleeping and have more anxiety now and I also feel flushed and my legs itch when I get up like I am holding too much fluid.

I also take Metoprolol 25mg twice a day. Are these a good combination?

I have had three Grand-mal seizures since 2002 and I am now 40years old. I work out with Cardio for 45mins and do weights for 45min three times a week. I have also gained 20lbs in the past month and I have had tests done on thyroid which I believe are inconclusive. I don't know what I should do?
