Advice & Tips: I found if I miss taking this medication, the nerve pain in my legs gets really bad. I couldn't function well if I took this medication during the day because it makes me really sleepy so I take it at bedtime. On a positive note, I sleep really well when I take it at bedtime because it keeps my legs from hurting and I'm using the sleepy side effect to my advantage!
