About a month ago I stopped taking my BP medication - Lisinipril. I've had this Rx for many years but always felt that it made me a bit tired and perhaps contributes to having a hard time falling asleep and headaches. My BP is better after adrenalectomy, but it's not great (avg: 140/100) so I still take it. But I just stopped completely to see if I could get it out of my system and how would I feel. Ah, no different, and perhaps BP contributes to this pressure I feel in my eyes. SO I took one last night, and of course, I wake up with a pounding headache. When I took my 75 Levo this morning, I felt nothing. Usually I feel more awake once I take it. So my question is, is there a particular BP pill that is the best for people w/Hashimoto's or hypothyroid? Lisinipril is an ACE Inhibitior. And I've read Beta Blockers may not be good. Does anyone else take BP meds and keeps a good BP with it?
