Ah yes, newbie bloat.
We all get it and yes, it's painful and frustrating but it does go away.
Some people seem to get better after a week, others it takes 2 or 3, but usually after the first week it does begin to diminish enough for a person to be able to cope with it.
More fruits, veggies, grains & legumes=more gas.
Try to make sure you are drinking enough water to help everything along and as for the soy, everything in moderation.
I usually eat something soy related about once a week, sometimes twice.
Watch any 'mock' substitutes as well, they also sometimes have soy in them.
Smaller meals, more frequently also seemed to help me somewhat.
Sending lots of hugs & hoping it subsides for you soon, I know how uncomfortable it can be.
