I am 17 yrs old, and am taking Lisinopril. Yes, I know I shouldn't have high blood pressure at this age, but I do and my average BP is 156/101. X.X Since taking this medication, I have been extremely tired (this could also be due to the fact I do not get to sleep until about 3AM) when I do get up I just use the bathroom and go right back to bed. Until about 4PM... I also have trouble getting to sleep. This may not have anything to do with this medication, but it sort of feels like bubbles popping in my stomach. I feel like I really need to pass gas, but I can't. When outside in the heat, I can actually feel my heartbeat racing. I haven't ever been able to feel it before. ~*+_Kitty_+*~
