I am a 27 year old male. I have had extreme excessive gas for a few months now. It is usually worst at night, maybe because of eating dinner, but not sure. It does not seem to matter at all what I eat, it happens every night. I am amazed at the amount of gas I have, it just keeps coming, I can feel it building up inside me and after I expel it it just happens again. I went to a Doctor and he thought I was probably lactose intollerent, but I don't drink or eat much dairy, and after he told me that I drank 3 big glasses of milk to test it and I felt fine. I do have some anxiety issues so I thought it might be IBS, but now I doubt it because it seems to be related to after eating, and also it happens at night when my anxiety is lowest.
This is becoming a very hard thing to live with because since it is happening at night it effects my romantic life, I have to keep trying to hold it in so my girlfriend doesn't notice. There has also been some changes in my bowels, I seem to go more often and they are loose. This is not as hard to deal with as the gas, but thought it might be important to help with a diagnosis. Everything I read about online says try changing foods that I eat, but I have tried all kinds of food and the gas still happens. I have never had problems eating any food either so that seems weird.
Here is a list of other things that might be useful in finding an answer.
1. I take Remeron 22.5 mg a day. I have been gaining weight because of this drug I assume, but I am not sure if these gastro issues started at the same time I started taking remeron but it was sometime around the same time.
2. Even though it is worst at night it is still common during a lot of days, just more noticable at night.
