Diet pills! Need to lose weights asap!!

Hey ladies! I'm struggling to lose weight. I was at 180lbs and wanted to be 150 by summer. Well I am only at 170lbs and I am being invited to beach parts and boating trips. I need to lose this weight sooner!!!

I am on the Mediterranean diet and exercising which is working... but I need some faster results. I wasnt sure if there were any diet pills or any tricks you ladies use to lose weight. Weight loss shakes? Meal replacements? Supplements? Anything work well for you?
