I have sleep apnea and I have trouble driving?

I have a vacation in September and I am planning on doing part of the driving on an 8 hour trip,my problem is the hypnotic effect it has on me and falling asleep,what is the best way to deal with this problem?

I would suggest going to a sleep clinic where they can usually do a test on you to make sure you have it. If you know you have it, you can get a CPAP (Continuous Positive Airway Pressure) Machine that tends to make a load of difference in people's lives. Other options include surgery or various other devices, but most people tend to start out with a CPAP to see if that helps.
I would highly suggest getting treatment for your Sleep Apnea even after your vacation because sleep deprivation has a number of negative effects on one's health including (but not limited to) low productivity, excessive sleepiness, and possibly even lower longevity. Sleep is a very important part of our day and serves a number of physiological functions that should not be overlooked. Good luck! I hope something works for you.
