constipation, chronic
"I have early menopause related constipation . 
For last 5 years moderate constipation . I've used lots of things - with success but also with fear of dependence . People have recommended lactulose as a non dependent choice. 
I take 30 mls night . It gives me a lot of wind . It does work but it is an accumulative effect that takes about 4 days of regularly dosing to start working and produce a bowel movement ... Not sure why so many others are lucky enough to get success the same day ???  ."
