Lisinopril and best time

Hi....I am a 48 year old male just starting on Lisinopril 10mg daily. Have taken it for 7 days now. Blood pressure before was 184/120 in the doctors office. Have seen it spike to 200/129 at the dentist plus 220/149 at the Oral surgents office removing a tooth. First day of taking Lisinopril it knocked down my BP too 123/75 thought that was great. Since has mellowed out now at 140/90. Im sure on my second visit the DR. will up my dosage which I will question. So far reactions have been that scratchy throat right of the bat that everyone discribes. Plus my stomach just groals the first hour as it trys to disolve. Takes about 4 hour before I can see it lowers my pressure any. Have been trying different times of the day best I can to find the best time to take it which I now have settled on right after noon lunch about 1 hour works best. I also have had alot of tiredness from it, which is different from the weakness I also get from a condition they say I have called N.A.S.H. (non alcholic steatohepatitis ) which basically is too much fat in your liver that drains me of energy worse each year. But why I bring that up is the feeling is different a tiredness compared to a weakness feeling I dont seem to like. The weakness I can jack away with some caffine but this tiredness nothing seems to help so far. Have had some dizzyness getting up which is something I can live with til it makes me faint or fall at some point then I surly will cry wolf get me off this. Getting blood work done soon to see how it affects my liver counts will update you on that later.
