Constant Acceleration at 1G is impossible for more than a few months.

From stationary in 353 days 19 hours 45 minutes 23.004 seconds at a constant 1G you'd attain c which is not allowed.

If you had an engine capable of producing a constant 1G which would also provide the illusion of gravity which would be nice for the crew, the trick would be to keep turning the ship around so you oscillate between (say) 0.75c and 0.9c so you'd still be prety fast but the time dilation would not be excessive and you'd have gravity (except when turning the ship) for the entire journey so no bone or muscle wasting.
