"i have been on saxenda for a week and a half. in this time the only side effect i&#039;ve had is constipation. the injections don&#039;t hurt, and i&#039;ve only had 1 small bruise. i don&#039;t know how much i&#039;ve lost as i&#039;m waiting to see my doctor for my check up, but i know i&#039;ve lost it as i can see it. so far i would recommend it to anyone. another great thing, this doesn&#039;t react with any other medicine. therefore i have been taking it with champix to give up cigarettes. i have not felt like eating to counteract the cravings, and have been smoke free for 2 days (i&#039;ve smoked for 25 years so this is a big milestone)."
