Not trying to flame here, but a "g" is a term used to describe acceleration.
When you're lying on your side (or anywhere else) you are not moving. No acceleration at all (w/respect to the earth).
I am not being accelerated while lying in bed. HOWEVER!!! I do experience a constant force that would accelerate me at 32 ft/sec2. So in that context, I feel the force of 1 G while lying in bed. Adding .3 more to that would be trivial, like having my middle son jump on me in bed.

later guys, gotta go fly from LGA to ATL (on DELTA with BOEING aircraft. only thing better would be Lockheed)
