That's a weight loss drug isn't it? As opposed to a diabetic aid? Ive seen it advertised as an injection pen, that helps you lose weight, but I have not tried it - Metformin works really well for me though.
Infact, in order to save money, the NHS switched me from actual 'Metformin' to a generic version (cant remember the name) and it was awful! I was hungry ALL the time, craving sweet foods and I was putting on weight in real time... Getting even bigger by the day!
Although it was the same ingredients, in the same amounts etc, the Doctor said that it was 'Cooked Together' in a different way... Switched me back to metformin, and the weight I gained dropped off along with my hunger issues...
So I'm happy to stick with the metformin personally - And one meal a day. It doesn't bother me to take the pills, and of course, here in the UK its totally free as well. If I lived elsewhere and had to pay every month for the metformin, then I may well be looking at finding ways to not have to take it, but as it stands, I take it, eat whatever I like once a day, and all is good with the world
