Hello. I have the same problems with my stomach too. Nearly everyday. My haematologist suggested small meals at smaller intervals. I have no gallbladder which makes things worse.
Some days I am so tired until the mid afternoon when I buck up a bit. I have it 13 years now.
I take 500 capsule every evening plus 1.8. of liquid in a syringe to top up to 608. That keeps my platelets level under 400 around 360.
I am a terrible worrier. My family help to keep me going. It could be worry which doesn't help digestion.
I play piano and teach on line. I don't go out to mix because of Covid which scares me. It's a shame that Covid happened because although I have all the jabs here in England no one know whether us people are covered at all! I put up with my tummy pains they are horrible and happen most days after lunch. I hope this helps to know I feel the same as you do. I am nearly 79.
