Hi K,
I took VT for 8 weeks here in the states. I found that it helps, and I continue my exercises. Here are a few i was taught.
Take a large ball and do circles with it while you keep your eyes on it. 10 times clockwise, 10 times counter clockwise.
Take two pens, keep them arms length from your eyes and about 18 inches apart. Without moving your head, move your eyes
back and fourth taking turns looking at the pens. Eventually go to playing cards, I used two kings and focused on their eyes.
Go walking outside, and turn your head left for two strides and then right for two strides, do that for 30 feet ( 10-15 meters ).
Then, do the same thing looking up for two strides and then down for two strides.
Someone already discussed the sticky on the wall, I'll repeat that one, I find it helps the most.
Get a sticky and draw a big "X" on it, put it on the wall, about 2 feet from you. Sit in a chair, keep your eyes on it and turn your head quickly
from left to right without taking your eyes off of the "x". Do it again but this time moving your head up and down. Work your way up to a couple of minutes a day. Try this standing up as well, but keep in mine the "X" sticky should be even with your eyes. I hope this helps, the exercises will make you dizzy, but you are challenging your vestibular system, which is what you want. I would do them everyother day, and remember NEVER GIVE UP !!
