I decided to give up milk and I'm on day 3. I feel rotten. Nauseous, dizzy, achy and odd stomach pains. It's the only thing I have changed in the last few days. The thing is I haven't completely given it up. I have had some cheddar cheese but I normally have milk in the morning at Breakfast. Yoghurt twice a day and milk at night before I go to bed. I would get up in the night and drink some too. So just seeing if anyone has had the same from given up milk?
