I am looking for the Fastin where it makes you jittery. I have tried numerous diet pills and I feel like the only ones that help me are the ones that has the side effects. I was on Adipex( Phentermine) and lost 60 pounds but the doctor took me off and I am starting to gain it back. I am looking for something that will curb my appetite. I drink my water and exercise but am needing something to curb my appetite.
