Brief Answer: Follows Detailed Answer: Hello XXXXXXX Thanks for your query. Eating foods that increase your saliva is a great way to get rid of the bitter or metallic taste in your mouth. These types of foods include citrus fruits like grapefruit and oranges. Drink more water as it helps to wash out toxins in mouth, and also to reduce acids in stomach which are both big causes for bad taste in mouth. If you really want to start a good day then you may drink some lukewarm water or lemon water. A cup of Green / herbal tea is also a good option to start a day. You can feel the difference within a few days, you will have a good effect on your health and you will feel so active and fresh all the day. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
