I have severe chronic RLS (restless legs syndrome) and have gone years without sleeping. Lortab was a MIRACLE! No other neurologist suggested this treatment and it worked immediately. However, I find that it's not lasting through the night as it did when treatment began. I am scared to mention it to him. I had searched for relief for my suffering for over 25 years and don't want to risk losing Lortab. I have tried ALL others. I take 2 daily.
