Hi only been taking this for 5 days just 10g but its making me feel terrible with horrible palpations about 45 minutes after I take it and lasts about an hour, there ment to slow the heart down so I don't know why this is happening and is it dangerous keep thinking my hearts going to stop,so I'm going to ring doctors tomorrow and ask if this is right apart from feeling sick and light headed that's my worst side effect just feel horrible , anyone know of this should be happening, thanks.
