My husband was prescribed it for post surgical pain after shoulder replacement last summer. He only took it for short period of time. Then he just took regular over the counter stuff like Tylenol. I think gabapentin was supposed to help with sleep too when dealing with pain. I didn’t know it could be for anxiety too. I don’t think it did anything in terms of anxiety as he was quite anxious worrying of not being able to heal right and work his job. But then he wasn’t on it long enough to take effect.
