Is it typical for people with NCGS or Celiac to also be lactose intolerant?

Please forgive my ignorance. I’m still relatively new to having any dietary restrictions. I found out midway through last year that it was gluten causing my reactions. My symptoms were extreme abdominal pain, all night - full body sweats, and a lack of appetite for days afterwards. The reactions got worse over a period of 3 years to the point I thought I was dying. Surprise! It was gluten.

I’m super cautious about my diet now. I’ll avoid certain get togethers with friends because sometimes it’s just too much. For the first 6 months I kept discovering hidden gluten, sometimes not even on labels. (Fuck you Louisiana Hot Sauce). I haven’t had a gluten reaction in months. I started gaining weight and having energy. I also made a career change and started learning a completely new industry.

I thought it was stress causing me to have digestion issues. I’ve had to take Imodium (diarrhea meds) every day for about 6 weeks now. I still have a healthy appetite and energy, no abdominal pain or night sweats like before. I started eliminating things from my diet to see if it was something I was eating. Once I got to dairy, my digestion issues fully went away. I haven’t had to take any Imodium all week. My wife is lactose intolerant, but has painful reactions almost like I do with gluten.

I have 3 gallons of whole milk in my house! This used to be a 1 week supply for me. My adult kids use a little, but it’s mostly me going through 3 gallons per week. I still crave it, but I know what will happen if I drink a glass (my go to) or have any cereal with milk, oats with milk, cookies and milk..

I feel kinda dumb now. I guess now that my stomach is no longer under attack I get to learn.

Are we just not allowed any comfort food?
