I took Corti-trim for months and months...recently (umm...4mo or so ago), I ran out and tried a similar product. I HATED the other one...couldn't tolerate it. It made me really sick, so I stopped taking it. I've been without CT for a long time and as of now I see no reason to pick it back up. I see good losses without it for right now. Maybe when I have a good money month, I'll splurge and get it again, but no time soon. SO in short...yeah it works, but the plan works without it too.
