question: I have been taking metformin 500 mg 2xday since April after being dianosed with type 2 diabetes. Just this week I have had severe diarrhea for 3 days but not in a row, I have had a little nausea and some acid reflux for which i take omeprazole as needed. Also my appetite has been up and down. Also mild headaches off and on this week and just a general feeling of blah. Just wondering if this could be related to my blood sugar or maybe something else going on. I am due to go get my bllod tests done but not until first of July. Any info is appreciated. Thank you
