Any tips for me to deal with the motion sickness in the beginning?
Try ginger capsules, they are among the few things against motion sickness without any piloting-prohibitive side effects. Your mileage may vary of course, but when I started my PPL training, they immediately converted my stomach from queasy earthling to Lt. Pete "Maverick" Mitchell, so to speak (unfortunately, just my stomach). Another thing that reportedly works well is a highly-dosed vitamine C shot, but I haven't tried this yet.
