I have not been diagnosed with IBS, but all systems are a little out of whack with the rapid(6 wk) 20# weight gain after
giving up smoking, and I was on chantix
for that...strange side effects
, but it worked. I can't seem to get anyone to commit yet that <span style = 'background-color: #dae8f4'>chantix</span>
played apart in it, since my liver enzymes have always been normal until 5 months after
beginning the chantix
...now,hmm can't remember, but the Dr didn't like the numbers..they were slightly abnormal I remember him saying.
