... nervous. I have chronic pain and have been taking vicoden ever since I can remember and I have been off it for 3 weeks and am trying this out. I guess I just want soo bad for something to work becausethe pain is unreal. So im just wondering what I should expect??? Ive read some things and I see quite a few people are very tired from taking it, so I should take it at night not right before work haha but what else should I expect when taking this medication??? Just nervous :/
