I'm far from being an expert on diabetes, only been diagnosed 18 months now, but I have to agree with Rie here. "Once or twice a day" doesn't seem right. Please take it exactly as it is prescribed for you at this time. Trust me, it will help.
As for morning sugars at 220, that's where I was diagnosed, roughly 12-13 mmol/L (Canadian). My doctor told me he really should be putting me on insulin shots at that level.
For the first few days, yes, that's probably where my numbers were, but within two weeks I had them down to 7-8 mmol/L (that'd be about 126-144). Granted he said that was extremely rare dropping that much that fast, but I was motivated, if you know what I mean!
Please get in to see a nutritionist/dietitian specifically schooled in diabetes as soon as possible.
We can do it!
