Splenic flexure syndrome

i am grateful for toby’s advice. i am 65 and have had gut problems on and off for over 25 years. have had sigmoid and colonoscopies, cameras down into the stomach, ct scans etc. Just told its IBS. ive diagnosed intermittent splenic flexure syndrome. ive tried fodmap diet, york test, exclusion diet but just lost too much weight and got ill from that. its really flared up now. i agree that deep breathing and meditation really help, as does walking and exercise, fresh air, calmness and trying to chew each mouthful lots of times, eating slowly, putting fork down between mouthfuls, not overeating, leaving table not quite full and no picking between meals and no alcohol. i find this so hard as i am a complete porker who loves their food and loves to stuff it in as fast as possible. hot water bottles help. im lucky as it usually only lasts a week or so but the pain keeps me awake at night and im always worrying about what i should eat. i suppose lockdown is contributing to this. I read that the homeopathic remedies: lycopodium, bryonia and china can help so im trying them. if anyone else has any self help remedies i wd be very grateful. Thank you
