Thanks for all the replies. Here are a couple of additional points about me.

1. In addition to RLS and a touch of PLMD, I have severe obstructive sleep apnea (OSA). My OSA is very well controlled by CPAP. As a general rule, sleep docs don't like to prescribe medications that have muscle relaxant properties to OSA patients. This is because of the effect on the airway muscles which could make OSA more severe. In my case, it might cause an increased CPAP pressure requirement. Generally, a high pressure is more uncomfortable than a lower pressure and may cause unwanted side effects.

2. I have a followup appointment with my doc in June. My prescription is for 1.0 mg per day. I quickly cut it back to 0.25 mg per day because it works so well. I have a concern that the doc may not want to prescribe 0.25 mg for long-term use. If he doesn't, he needs to prescribe something and not leave me hanging out with limited sleep.
