OK, I understand a bit more now. Once or twice a day to have a low (under 3.9/70 is low and under 2.8/50 is a hypoglycaemic episode), is too many lows for a Type 2 on a sulfonylurea drug. I can actually see why your DE was concerned. That you could get as low as 1.7 is another cause for concern as, it's not common for Type 2's to reach this low a level without reason (i.e. missed/unbalanced meal, medication dose incorrect, etc.).
You shouldn't have to "feed the medication"; eating just to keep your blood sugars up. That's just a recipe for disaster and not a way to live in fear of lows all the time, especially over night (a whole lot of reasons why that's bad). Along with some conscientiousness towards diet and exercise, meds should help stabilize BGLs throughout the day without causing lows.
Again, it's the balancing act
This new drug may not be your answer but glyburide may not be either (or at least not the dose you were on). It's can be frustrating and challenging at times trying to find out what might work but patience and perseverance will eventually get you there. Keeping a daily log of food, meds, exercise and their times and amounts is the best way to see those areas you need to address and (IMHO) the only way to know what's going on.
Just to share a little and maybe give another perspective.... I'm a Type 1 (5 year anniversary yesterday), on "intensive insulin therapy" or MDI (multiple daily injections) and it took me a couple of years of trying different insulin and regimens to get me here. I test 5-7 times a day and inject 2 types of insulin 5-7 times a day. I've never had an A1C below 7.9%. I regularly have multiple daily lows and highs. I eat moderate carb (100-130/day) and have maintained my weight at 110, give or take a few up or down for short periods. This background info is mostly just to say that, despite managing my diabetes every few hours of every day and doing the best job possible according to my D-Team, I doubt I'll see my A1C ever below 7%. I'm still trying to prove them wrong but, as a "brittle" diabetic (old term but still used) the wide swings in BGLs I experience hourly, make that a difficult challenge.
Wait a few weeks, keep a logbook in the meantime (medical folks can't dispute data
, make an appointment if you're not satisfied with your numbers, then try the next med or dose. Metformin would probably be the next most popular drug to try. But... one step at a time. Hang in there
