Hi, I am 68 year old female. I just got dentures 6 months ago. I take several medicines , gabapentin 300 3 a day, hydrochlorothiazide, metformin 500 twice a day, lisinopril 20 mg 1 a day, glimepiride 1 mg 1 a day, atorvastatin 40 mg 1 a day, carvedilol 25 mg 2 a day, and amlodipine besylate 5 mg 1 a day. I have a very bitter, ink-y taste in my mouth only when I drink water. This started 2 weeks ago. My AC1 was 6.2 2 months ago. Thank you Christine Allard YYYY@YYYY
