Hi @rigsby71
A quick consultation with Dr Google reveals a long list of possible causes, gum disease, medication, covid 19, allergies, b12 deficiency even anxiety. Not everything is caused by T2, so even if someone on here had the same symptoms there is every chance it would be for different reasons. Your best bet would be to get yourself to the dr's to get a proper diagnosis.
Hi. If you are on Metformin that can cause a metallic taste as it did for me for 6 months. That beer intake is a bit on the high side as beer is high in carbs. Make sure it has a low alcohol content.
As mentioned above, you need to get checked out if you're uncertain. That said, it generally takes quite a while to get to actual liver failure, so I'd be fairly optimistic. If you have been stressing your liver, it might be a good time to give it a chance to repair.
