I've been coasting for about 3 years now trying to manage the sugal levels
with diet and exercise alone, but that doesn't seem to do it any longer.
Part of the problem is not being able to exercise because of needing a total
knee replacement, which makes it uncomfortable to walk and ride my
stationary bike.

Anyway, she started me on 1/2 tablet of 500 mg metformin once at day with my
evening meal. So that's just 250 mg of metformin. I felt nauseaus on and
off last evening and today, a bit dizzy, but nothing really bad. I don't
like feeling this way though. Now...my question is....how long does this
medication take to begin to work? I'm not seeing a drop in my sugar levels
last night nor tonight after eating. It actually seems higher than it used
to be. Is that possible?
