That is not a recommended process, you will have performance issues and you'll be losing all the advantages given by the full recovery model.
Once I found a company where they did that from time to time but never did any log backups (the recommended practice), so my suggestion was to change definitively to the simple recovery model.
Depending on your situation, you should be taking log backups and defining a correct log size or change the recovery model to simple.
Maybe someone will explain with more detail.
