Gumdrop,
This is a sensitive and sometimes embarassing subject for many. Please know that you are not alone in experiencing this withdrawal symptom and there is much you can do about it.
Smoking increases gastro intestinal motility(how your intestines move)when you quit, you intestines slow down. Your food spends more time traveling through your gut and naturally produces more gas.
Try cutting out foods that naturally aid in gas production, carbonated drinks and chewing gum. More air swallowed, more gas you'll have. Lastly, regular physical activity has also been helpful as it encourages your gut to start moving.
Hope this helps and please feel free to share what tricks have worked for you,
