I agree with gibblet and Ausie on the contacting us and getting off the meds.
Depression can be a bigger problem than the surgery itself.[

Definitely feel free to contact any of us if you need to talk about any of it.
The meds can hamper you if relied on too long. The more positive you are the more you will find that you do not need them as much.I think that often pain medications go hand in hand with depression.The more depressed one gets the more we feelpain from an injury or surgery that we otherwise would not feel if we weren't depressed.
Keep in good spirits and remember that after it's over with you will be in better shape than you are now.
