"i am just on my second day, i took a contrave er yesterday and this morning.  so far the only side effects i have noticed is a little brain fogginess in the morning (i am drinking an extra cup of coffee to combat that) and a little more thirst, which i am sure is a good thing if you are trying to lose weight.  i was a little put off by contrave er when i read some of the side effects that some people have had (nausea, sweating, gastric disturbances, feeling jittery) but as of yet, and i know its early, i haven&#039;t experienced anything like that.  i also noticed i felt fuller sooner when i ate my breakfast this morning. so all in all, i would give it a thumbs up."
