I agree with this remedy. I use both grips and gloves. Another thing to consider would be to add bar ends to give your hands a few extra positions. Also, as you ride more, you'll find ways to alter your grip on the bars to reduce hand fatigue. Finally, try to ride without putting a lot of weight on your hands. This may mean altering your seat and/or handlebar. It may mean strengthening the core. Try riding one-handed for short stretches (practice with each hand). It's a good way to increase core balance.
