The maximum recommended dose of Imitrex is 80mg per 24 hours. If you are taking more than what is prescribed to you, it might be the sole cause for the rebound headaches. The best treatment for rebound headaches is to stop the pain medicine, at least for some time with your doctor's advice, or to change the medicine.
