I just got my Metformin from my doctor. But I wonder if this really work on me to lower my glucose after I ate a meal. If it does how long it takes to take this on effect? I'm worried about not having my sugar down after each time I eat a meal. I wait about an hour after a meal then measure my sugar but it's still high about around average 230 mg/dl. So because I'm much worried of this high rating I didn't take chances that glucose would linger on my system. I essentially did wanted to take this medicine work as late before glucose does harm to my body. I started to walk at least 1.5 hour then it goes down to less than 100 mg/dl. I wonder if Metrofin has some efficacy to lower my glucose, or it is that my walking exercise is the one that does the job of lowering it. I can't make any distinction of it whether Metrofin is working or not. If it is did anyone knows exactly how this Metrofin works, and how long to get this take on effect on lowering glucose after a meal? Please reply anyone who is familiar to this. Great thanks!
