I suffer with ibs , i get weird symptoms , like my guts hurt when I'm in bed asleep and keeps me awake, 

i don't get constipation and I don't eat food containing wheat and dairy  , 

i thought the diet was the problem so I stopped eating certain foods because I thought I had a allergy but it helped, but I still get the pain at night like my guts are being crushed and I need to pee loads at night and drink    Water 

also I don't seem to have any problems during the day only nosey guts
