Hi, I am sorry to know you ve to live with restless leg syndrome. Horizant is the brand name for generic Gabapentin enacarbil. It is a patent medication, not the same as gabapentin. Unfortunately, its use is associated with drowsiness, sleepiness, blurred vision, etc. This is a prescription drug, so you need to get it prescribed by your neurologist to start taking it. If side effects will affect your daily activities, should change therapy. I d also recommend to schedule physical therapy seances as you can get profit of them. Wish fast recovery.
