Are There Alternative to Bite Blockers?

I had my braces put on yesterday. The braces are fine but the bite blockers are very irritating and causes me not to eat. I do not want to wait until they "go down" from eating because I don't know how long I will have these blockers due to my treatment needs. Is there an alternative? It is already tough for a person to go through the treatment and to have to worry about eating is just another stress factor.
