Man, that's rough.
I never had a problem. If fact, between the time the engines were started, to the time we taxied for take-off, I was usually out. I was awakened more than a couple of times by our WSO asking me if I'd like to join them with the checklist (they asked me if I was ready to go, I responded that I was ready to go - real mission critical ;-)). The only thing that sucked about it was that the computer monitor I sat at the most was located right next to the power bus. The EMI coming off that bus really screwed with the screen. It was like constantly degaussing it - it was always wavy and distorted. I think it contributed to my first (and last) upchucking on a flight.
