J-Pouch Gas Elimination

I had my takedown about 10 weeks ago. Adjusting has been a little rough as expected. I’m overall happy with how things are going. The only real complaint I have is trying to deal with the gas. I frequently get pain / pressure from buildup of gas, when I go to expel it on the toilet, most of the time only stool comes out. If I don’t lay on the floor after, tucked up in a ball, the gas just stays inside. This isn’t as big a deal when I’m home in my own bathroom, however, it’s not something I look forward to doing when I have to use a public bathroom. I’m curious if any fellow j-pouchers have had similar experiences and learned how to take care of the gas without doing bathroom yoga? Or maybe it got better with time?
