Hi I'm sorry to hear of ur troubles with metformin, mine has thankfully settled and I tend to eat nuts ie a mixture of almond , brazil and cashew nuts crushed to help with fiber rather than weetabix that was toxic for my stomach , I mix it with alpro plain zero sugar youghart and this has helped settle further my loose stools that were very watery and loose snd had helped bind them . I get the 200g bags of nuts from lidl and crush them , 6 brazil nuts , 30 grams of almonds and 30grams of cashew with 150 g of alpro plus a sprinkle of powdered cinnamon but be careful to just break urself in with cinnamon as some can be allergic to it. . Do u take the metformin mid meal with a glass of water , I take one 1/3 way into meal and the other 2/3 rds into the meal . It seems to suit me better. I'll introduce rolled oats into my breakfast as I'm weary taking cereals due to the weetabix scenario, however I have started during the day to take small spoon of granola oats once a day. Then twice, then three times to build up a tolerance of to see if I'm intolerant to it as metformin is a strange medication that works with some foods but not others. I wish u health in ur endeavours my sincere regards
