At 3 weeks, you're certainly entitled to whine! Actually, I think after having brain surgery, you're entitled to whine whenever you need to!
I had my surgery in February. I too, lost hearing in my right ear, dealt with the incredible pain and inconvenience of the dry eye, still can't wink and would probably benefit from a sippy cup. We all get impatient for things to return to semi-normal, but unfortunately, nerves work when they are good and ready and they don't seem to care about our time schedules! At 3 weeks, I still looked like a train wreck (and felt like one), but I've had surgery to fix the dry eye thing and can smile enough so that people know I'm smiling, so things do improve... slowly....
I still have to drink through a straw or I wind up wearing whatever was in the glass. Soup is not a pretty sight either - I don't think I would order it at a restaurant unless they provided a bib and a dropcloth. Of course, with my 2 little ones and my husband, we could probably use the dropcloth anyway.
My surgeon told me before my surgery not to plan to go back to work until at least 3 months post-op. I'm a stay at home Mom, so technically, I was back to work the day I came home from the hospital, but there's no way i could have handled a job outside the home. Hopefully, you are able to take the time off of work that you need so you can ease yourself back into it and give yourself time to heal.
Don't get discouraged. It's still early in your healing process. Slowly things will get better and you'll feel like yourself again. I know it took a while for me to feel like "me".
Take good care of yourself and don't push too hard!
