hello, re: victoza i was on it for about a year, never felt sick, didn't suppress my appetite, got my readings down to a fabulous level-then it started to level off and wasn't working so well and readings crept up was on metformin slow release at the same time.. finally i pretty much begged my gp for insulin as i didn't want my readings to continually be high, i actually had been requesting insulin for about a year, to help protect the cells i had left.... so finally i'm off victoza and started lantus today keeping metformin as well so that's my 2cents on victoza.. ps didn't ever like the idea that a side effect could have possibly been cancer.
