As you aren't a rigid body, there shouldn't be any more significant delta in pressure than if you let it go topside. That said, it would be a smaller volume of... er, offgassing... at depth due the increased pressure.
The school kid in me was somewhat bemused when my Rescue materials actually mentioned eating gas-producing foods as a potentially bad idea due to the possibility of producing gases at depth which would (obviously) expand during ascent, potentially causing a painful (or in other ways unpleasant?) situation.
I couldn't help but wonder how much misbehaving food one would have to eat to experience buoyancy problems (or a runaway ascent). Incidentally, could you on-gas the methane (etc), and if you did, what is the narcotic potential of methane?
