I am doing the same as you given foot cramps related to Parkinsons. My dose of the extended release carb/levo (Crexont) is 52.5-210 taken at bedtime. Is that your dosage? Doesn't always get me fully through the night but another approach is to take your standard daytime dose before bedtime and another at 2-3 AM... IF you are getting up anyway for bathroom issues.
