Is there any harm in eating ice?
Well I can tell you it is good to eat ice because Ice is frozen water so your body will be hydrated all the time 
That is exactly how I feel about it. 
The only thing is you need to be careful with your teeth since ice is a hard solid element so please be careful and if possible ask your dentist 
I only eat soft ice.  I believe Sonic is the most popular ice at a fast food restaurant.  What do you think?
Moderation is the clue. Sonic is a good fast food restaurant, hamburgers there are yummy good choice!
It is definitely an addiction.  It could always be something worse!
Could you please tell me when and how did your addiction for ice start?
I honestly don't know.  I think it was when I was on a diet and decided to eat ice instead of junk food.
Well good job is better to eat ice than carbohydrates 
Thank you!  Have a good day.
