Will Benadryl (diphenhydramine) work for motion sickness? I am going on a long road trip and I get terrible carsickness. Will it work the same as dramamine?

Hyoscyamine sl. Hyoscyamine 0125 mg sublingual is a pill with the same pharmacologic action as scopolamine, but you do not have to purchase an expensive patch. It works usually in about 10 minutes after symptoms start.
