i am currently on 25 of levo and 15 of carbimazole. I have Graves Disease and am on block and replace. Lately experiencing very windy tum by the time midday comes. Get extremely bloated and very windy and have to rush off. OK for four days of the week because I only work mornings but on a Friday I work all day and found it most embarassing. is it likely to be what I'm eating or meds?
