I was eating kraft dinner last night and had a forkful of it and suddenly got this weird metallic/soap taste in my mouth. I figured it was just the fork had a taste of soap on it after my step-dads hack job with the dishes. A few hours later it still feels weird. I go to bed, and wake up in the middle of the night feeling like I'm about to puke and the metallic taste strong in my mouth. Next morning (today) I woke up and still have the taste and an upset stomach. I feel like I'm about to puke but I haven't yet. Any ideas what this may be? Not pregnant, and had dental work last month. (fillings)
