Thats funny because i ate dried banana chips today for breakfast, just a handful, but it really helped the nausea from my metformin. First time i havemt thrown up after breakfast in 3 days ( i jad been drinking protein smoothies and that did not mix well). Bananas help me with nausea after dinner at work too when i take my second dose of metformin. (I worl evenings where there is a kitchen i have access to, an assisted living house for the elderly).
