Overwhelming body symptoms and conditions

I was just started on lisinopril two weeks ago for slightly high B/P, but I was freaked enuf about it to try a drug for the first time. I have had the most overwhelming body aches, especially when first getting up from sleep (and I was having serious insomnia issues as well, which were being tackled too). So, I am finally getting some well-needed rest, but when I get up I feel awful. Creaker than my 100 y/o grandpa! I switched to taking it before bed because I also had what I would describe as "equilibrium" probs; now, I flunked the balance beam in gym, BUT, I am not completely out of it. I am truly wondering if the lisinopril is worth it. I would probably like to take something else, even if I have to pay for it out of pocket (ouch, but worth it to take the best on the market, I think). Any help would be very much appreciated!!!
