Stoma: going to work, noisy stoma and pancaking issues!!!

I've had a stoma for 3 months following emergency surgery. I'm still struggling with the whole thing although I've been told it gets easier in time. Whilst I am going through treatment I still go to work most days. This involves wearing a suit and sitting in meetings. My issues are twofold:

1) Noisy stoma: just awful. I've tried charcoal tablets, jelly babies and drinking peppermint tea by the gallon. And still we have very embarrassing situations. Any advice??

2) Wearing the stoma to work. I've got some boxer shorts which come up high and strap in the stoma so you can't see it (good). However when it starts to fill up I have a major pancaking problem which results in a split bag and its a total nightmare (bad). Without using the stoma-friendly boxer shorts I tuck the bag into my trousers. This means the waistband/belt cuts the bag in half so the waste doesn't trickle down to the bottom of the bag. Again, a pancaking problem and potential split bag. 

The whole situation is a total nightmare and I've started to work more from home just so I don't have to go into the office. Not ideal long-term. 

Does anyone have any advice or have faced similar issues? 

Thanks!!!
