Hi, I'm in week 9 too. I've had a cold but it wasn't a bad one, apart from occasionally feeling dizzy if I leave it till too late before having any packs...and pretty much constant dihorrea I've been good. I don't think it's the diet really as you are getting probably more vitamins and minerals than you ever were on food. Think you may have just been unlucky getting these bugs while on the diet. However I think you do tend to feel more vulnerable on this diet, and more cold. Normally when ill I'd treat myself to nice foods, hot drinks and soups and lots of cough sweets and cos you can't have them on this diet you may just feeling that little bit worse. Don't give up though you've come really far now and hopefully you'll be feeling much better soon. Look after yourself and have lots of hot baths and watch movues under your duvet...guaranteed to make you feel better I reckon
