Can someone answer this?

Okay starting in 2014 of august I noticied that my hands were shaking,but weird thing is i've noticed once I pop something in my mouth that is sweet it slows it down,Now i've been to the doctor about this but we never really talked about it for long it was my sleep well lack of anyways that was our main topic.So whats the reason behind this

Also I told my dad about the eating something sweet and it slowing my shakiness down he said thats kind of a bad thing but never told me what it was.
