For digestive problems try mct-oil and probiotics. Both provide healthy gut bacteria and should help with digestion. The oil increases your calorie intake approx. up to 100-300calories. You start to burn more (it's also used as fat-burner), hence eat more, which is good your stomach gets larger and that helps you with gaining weight. I use it and it helped to build almost fat-free muscles, but that's maybe genetic so not sure here. Mostly the sleepy problems are due to digestive problems or the insulin, that increases when you eat high glycemic food. Maybe try to eat more low glycemic food they are digested slowly and less high ones
I already get MCT in the coconut oil I have every meal. Also, I drink Kefir with every meal. You probably don't even know but kefir is a probiotic.
Seriously, there is very little you can suggest that I haven't tried before.
I already eat low glycemic foods. Oatmeal and whole grain bread with sweet potatoes. That's as low G as you can get.
So yeah. I appreciate the sentiment but not the advice. I been through all this before. It's tedious to get advice from members who assume I don't know or haven't tried anything.
In other news! Went to the gym today. They tell me unless I have my second vaccine shot, I won't be able to workout there after the 25th. So stupid. The vaccine does not stop the spread nor does it keep you from getting covid. So why is it mandatory? Currently looking for alternative gyms or to do home workouts.
