I have to take pills for it cos I get incredibly dizzy when I get up (I once fell down the stairs because of it). My blood pressure is alreayd way to low whe I'm just sittin down and then when I stand up it drops eve more.
The pills I take are caled Regulton. It's prescription though. You should see your doctor if it's iterfering with your everyday life (like with me. I have to stand still for like half a minute before I can see again. it just goes all black when I stand up. it's really embarassing when I'm in public and I just stand there looking at the ground

)
