Hello, i took a diet pill now im feeln vry anxious n head is hot,my body is cold,whats d best way to get rid of this feelin or flush out d medication?

Don't take any more: Many diet pills are full of stimulants like caffeine (in an attempt to increase your metabolism) such that you end up feeling anxious. Others are full of laxatives to make you poop more than usual. However, none of the diet pills that are dietary supplements really work (you'll see FDA warning label). This is different from OTC medications which are approved for weight loss eg Alli
