Great - keep it up
Yes it will make you feel worst but just remember it will pass after some work at it. The Physio lady said it will take some dedication but it is possible. Its time to take control !!
Yes having someone drive me round in the car just about made me feel like I was going to bvomit. LOL I reckon having vertigo points out just how bad some peoples driving is. LOL
Please get your inner ear checked first tho, she did this weird thing on me to check the "rocks" in my inner ear but apparently once someone does this thing on you you have to not lay down flat for a couple of days to let it settle. i,e including sleeping. It is probably the MS/vertigo though but just to make sure your not doing exercises for nothing get it checked.
Try some ginger in your diet to help you on your way - supposedly helps with nausa. You could probably get a pregnacy formula tablet that includes this. They use it to help with morning sickness so why can't we use it if we feel sick. LOL All other medications just drug you out and make you sleepy.
Good luck with it all
