By early afternoon the inside of my lips feel swollen, especially the upper and I start pushing my tongue into my bottom teeth over & over.I do sleep with my mouth open at night. I am female, age 76, and weight 138 and am 5 3 tall. I have a pacemaker since 7/10. Am on BP medication, Chlosterol meds, blood thinner and Dilantin. Had many mini blackouts 3 year ago, but no longer.
