Dizziness is one of my most pronounced symptoms. I am so dizzy by 10:00am or so (or earlier if I exert mysself at all) that I have to force feed myself until later when all is done and I can have my MJ. That is the only thing that works for me. I even (almost) had to quit drinking. I really like to drink. I'm a wine collector. I only have about 50 bottles or so, but it's a start! The only reason we have that many is that I have cut back so hard. I will have 1 glass or 1 beer sometimes, but I mostly have to do without since I am so dizzy. It's absolutely one of the most annoying symptoms. I'm usually ok if I'm sitting, but sometimes I'm dizzy even then.
Believe it or not, exercise also really helps. It helps my eyesight too and helps so many things. I liken the mechanism of the exercise to "pushing past the symptoms". What I mean is that my eyesight and vertigo will really be awful while I exercise, but when I'm finished I cool off to a baseline like I have in the morning when I wake up. I've even started taking cold showers in the morning (which sucks) so that I don't make myself dizzy. I then absolutely maw down on some food. They say it's the most important meal. It is for me that's for sure because it's the only non-MJ induced time I feel like eating.
