Don't be afraid to let waitstaff know that you have special dietary needs. I had gastric bypass 7/2011 and we took our 1st trip in mid-Oct for my birthday. I am not one of those pushy demanding customers and could adapt from what was on my plate but the waitstaff at each restaurant were very sweet about making minor changes. For instance, at one place, I ordered a baked sweet potato normally served with whipped butter mixed with cinnamon & sugar. The waitress brought me the cinnamon bottle from the kitchen and I mixed some with Splenda instead and passed on the butter. Amazing, someone always knew someone who had weight loss surgery and they were so willing to help. They all earned great tips.

While in the car, pack a cooler with the RTD protein drinks, protein bars, and bottles of water. Freeze the bottles ahead and they will keep everything else cold while they thaw.

Most importantly, enjoy and take lots of pictures. You can use them for comparison along your journey.
