Gas question

Not sure if this has to do with BFing, but DS #2 has been extremely fussy for the past 2 weeks and just cannot settle.  He is constantly crying if he's not being held upright and needs to be held for about 30 minutes after BFing in order to go down. Even at that, he wakes about an hour or less later crying... and a painful cry at that.  Pedi says not to worry, as he has a healthy appetite, is gaining like a champ, and is not in pain WHILE nursing.  Anyway, DS #1 had reflux and meds helped a bit... but it wasn't this bad.  I have cut out all foods that I assume might cause this reaction and still he seems upset.  Gas drops never worked either, but did anyone have success with any sort of gripe water, etc?  For the record, he is 6 weeks old but was born a month early... so is technically (by his due date) 2 weeks old.  TY!
