I have the slow motility and gastroparesis too, but I ended up having to have a g-j tube. Most of the time I can only eat small amounts. I try to get in as much protein as I can, but it really tolerate saltine crackers the best. They seem to calm my stomach better than medicine.
I can't really make any good suggestions as I am currently losing weight. I have been having some kefir yogurt every day to try to restore my good bacteria that was wiped out by all the antibiotics I have been on.

I've been battling the same thing for a awhile and got some helpful tips from folks here. It's getting better a little bit at a time. I don't drink milk anymore, I eat fresh organic foods. A lot of fresh fruits and veggies, very little sugar, more fish, meats and chicken with no antibiotics or growth hormones, only natural grass fed. Right now, it's hunting season, and I've been eating venison for some meals. Some say it is going a little overboard, but it's definitely working. Smaller meals about every 3 hours. I play around with my eating a lot, because it is hard to figure out. My pcp has prescribed pantoprazol also. It's for acid reflux, which I don't have, but he said that with our swallowing difficulty, we tend to take air into our guts, then with our slow digestive systems, and the type of meds we are taking, we develop pain and discomfort. Pantoprazole aids in keeping stomach gasses very low. Like I said, all this has definitely helped. Chewing sometimes can be a problem, and swallowing is still an issue, so sometimes it has to be soft foods, no choice.

I totally agree with TBreak, you really do have to find what works for you. I was diagnosed with Celiac Disease over 10 years ago and have found for me, in order to keep my gut working regularly, I have oatmeal with cinnamon every morning and I carry a water bottle with me so I can take sips often. Since the MG, I am back to tweeking the diet, and with my activity slowed to a snails pace, the water, fruits and veggies are even more important, along with protein for energy. When chewing and swallowing is an issue, a nice bowl of homemade soup is the ticket. I hope you find what works for you.

My daughter has a GJ tube after fighting severe gastroporesis and repeated respiratory infections due to aspiration.. My problem is more with reduced esophageal motility and swallowing which have worsened a lot in the past months. I have been working with a speech pathologist on both exercises to strengthen the voice and the muscles used in swallowing. Diet changes were a must and I am still working on it and have been planning to see a nutritionist.

The only fresh fruit I can manage is a banana. I have given up most meats. Cottage cheese is a good protein source for me. I managed small pieces of turkey at thanksgiving if I had gravy. Veggies can be cooked and mashed. Sweet potatoes, mashed potatoes, carrots are easier and I whirlygig the cooked peas or green beans.

My weight has fluctuated a lot as I have had limited activity this year due to 7 hospitalizations, 5 of those for surgeries. Most of those were followed by restricted activity and odd diets of puddings and such that did not help my weight at all. I am looking for more protein sources and think I may try some protein powders.

I do manage to have bran everyday by soaking it in milk. For someone who has gastric problems that would probably not be a good idea due to the fiber but for me it works well. So much of this is trial and error and needs to be individualized. My lower GI tract had started slowing but the pyrido perked it up enough for now.

I will look forward to seeing what ideas others have come up with.
I also use egg salad and tuna salad by mixing mayo with mashed egg or tuna.
