Ewhitese,
Just a suggestion, but don't throw in the towel just yet. I had GK this past April and I also experienced sharply increased dizziness and crushing headaches at about 3-4 months post-GK. My symptoms lasted a good 2 months before gradually subsiding completely by September. Granted, we all respond differently to these procedures, but I am now completely free of all post-GK side effects. I am 52 and work in a very demanding profession. I expect to work another 15-20 years because I enjoy being challenged and I think I have something to offer to my employer and our clients. You might find others on this forum who share the temporary setbacks after GK, as well as the longer term recovery (Robin comes to mind, for example). For many (not all), recovery has as much to do with having a positive attitude as it does to do with the adversity of side effects and temporary setbacks.
(Maybe in addition to the Watch and Wait Brigade, it's time to start an "I refuse to let this #### tumor define or limit me, Brigade!")
Best wishes and Happy Holidays!
Petrone
