It IS winter time, so the nosebleeds could be from the dryness. One things that I find helpful is called Ayr saline gel. It's a saline gel that helps sooth dry nasal passages. I'm not sure if available in Scotland, but can't hurt to look for it or ask the pharmacist if there is something similar.

Keep in mind that your entire body is under a huge amount of stress right now, which can exasperate everything. You may not normally have nosebleeds from dry winter air, but under this new stress, you may now. And there is still the question of whether you have sero-negative Sjogren's...which certainly would cause dry nasal passages.

The withdrawal from Cymbalta can last a while...weeks. Especially with the quick taper. Your doctor is wrong to assume patients will be fine with a short taper and probably just dismissed any real plan because he/she didn't want you to get off it. So if you decide to drive on, then give it some time before you assess what your real symptoms are, as you won't know until the Cymbalta ordeal is over, out of your system completely, and your body recovers.
