Hi Kajmeister,welcome to the forum.If you are taking prescription drugs with you get your doctor to write a letter stating which drugs you are on,you may have to pay for the letter.Take enough with you for your visit.Drugs in the US often have different names so it will save confusion .The US use a lot of corn syrup in products so this would be one thing to look out for in bought foods.they also calculate their carbs differently so carb values on things will also be different.As you are diet controlled you will have to watch the portion sizes that you eat over there as well to try and keep your sugars under control.Do you have a blood test monitor? If you do make sure to take enough strips with you.In the US they test differently by using mg/dl instead of mmol/l like we do here.I'm not sure what you mean by restrictions though?
