I've been having dizzy spells this year, especially when I stand up. The doctor said I have low blood pressure and recomeded that I eat more salt and drink more water. I've always had low blood pressure, but I think the Tysabri may make it worse, so I've started pushing out my Ty schedule by two to four days each time.

Either the salt or the less frequent Ty is helping.

Anyone else have this problem?
