I'm not sure how you can have a masters before you student teach. Generally, you student teach with your bachelors degree.
If that's what you mean, you can go on to get your coursework in ESL or counseling or something like that, which will allow you to work with children without having to teach all day.
If you really do have a masters degree in education, that's kind of a lot of work and expense to decide you don't want to teach after all. Give it a try for a year or so and THEN decide whether or not you wish to continue doing it.
