I have been diabetic for 12 years and moved to Spain 3 years ago. I am on Lantus at night and Humalog with meals and test 4 times a day and until recently have not had any real problems. However I now have a new doctor just taken over at my health centre and he will not prescribe enough test strips for me saying that two times a day is enough and has put me on metformin 500, 1 tab a day. I am very worried about giving myself insulin without knowing what my sugar level is and I do not know what the effect of taking insulin and metformin is - should I decrease my insulin intake. My doctor has no english and my spannish is not good enough to cope with medical problems. HELP
