I feel for ya.... I know I am wake several times a night but I also have the option of taking a nap during the day.
Did you take your nerve meds at night or in the morning? My doc told me I should take them in the morning as they have a effect of tired for only about the first 3 to 4 hours then there is a burst of energy. I take mine at about 7 or 8 in the eveing in hopes that the burst will hit be before bedtime. I wake up all hours of the night sue to this back hip leg pain tho.
I hope you get some sleep soon.
