Camilla, Yes, we've had problems with low blood pressure also. Keeping a log helps to know when to be careful about blackouts. My Dad's is lower in the AM, and then his more active times are in the PM and his BP goes up. Make sure you teach Peter to stand up slowly, wait awhile before he starts moving. I don't know if it is PD, but my Dad seems to sometimes LURCH out of his chair, and almost trot across the room - and the take-off seems to be when he blacks out. We are also adding salt to his diet. But the doctors all say that your BP can't be too low - it won't kill you. What did make it worse was when Dad started taking hytrin for his frequent urination problem. We had to cut that down to one a day. Once again, it is a trade off - when we control the urge to urinate - it drops the BP too low - cut down on hytrin and he's piddling all the time - Oh, well... I'm not sure if it works for everyone, but watching Rush Limbaugh makes my BP go up! Just kidding!
