I went to the docs with breathing difficulties,I put weight on over the last 7 years following a motor cycle accident driven over right hand side so cannot easily exercise , so long story short diagnosed type2 about 12 weeks ago lost a stone so far , low carbs, then put on metformin. side effect difficulty breathing chest pains ? , now met mr same side effects? Do these doctors know what they're doing , it seems they have there own agenda and your newly diagnosed what do you know! . Still can't walk upstairs without gasping no I don't smoke. Are there any other meds? That maybe more expensive they don't want you to know about?
