Has anyone had this? I can't really explain it but it just tastes stale. Even when I've brushed my teeth, I can still taste it. I'm trying to eat well but the majority of my diet at the moment is made up of carbs and I'm drinking a reasonable amount of water (2 litres so far today) so it can't be dehydration.
I'm feeling really nauseous but haven't actually been sick yet. Could it be linked to this? Would be interested to hear if anyone else has had this.
