answer:Sure, when I was a teenager and young adult, I tried just about anything. So did my friends. Most of us were left feeling sick, strung out, heart palpitations, sweaty, nauseated, the ones with caffeine caused headaches from withdrawal, the list goes on and on. Any weight that we lost from taking the pills came right back as soon as we quit taking them. Those things will mess with your system, it’s not worth it.
