Hi Pepper, I'm so glad that the test wasn't as bad as you thought it might be and thankfully it's all over now. I hate when test results take so long and it's great of your GP to be trying to get them earlier! Kudos to him. I am not sure what is causing your jitteriness and other symptoms, but maybe it is the withdrawal. I could just be coincidence, but I am seriously doubting that, especially with the timing. Its' a shame, too, especially if it was helping you at all..and now to debate whether or not you really want to keep taking it. Nothing is ever easy for chronic pain sufferers, thats' for sure.
