Thanks to all of you who replied; I've read your posts, and the consensus seems to be to hang in there, take shorter rides to get acclimated to the new riding position, make adjustments to the hardware if necessary. All good advice!
For the record, to the poster who delicately inquired as to my age--the 'special birthday' is 60. The handlebar is a Nitto Dream, and i was mainly riding on the ramps and hoods and can certainly appreciate that having a variety of hand positions will be a definite plus over flat handlebars. And i was, indeed, wearing a visor!
The weather report for Labor Day weekend calls for beautiful riding weather here in Western PA, so quiet country roads, here i come.
Thanks again, one and all.
