Hello dear 
I evaluated your query deeply.
@ You can take tablet 
bisacodyl (5)mg at night as single dose to get 2-3 
    evacuations next morning . take care not to exceed the dose or repeat it
    blindly which can cause 
dehydration levels.
@ Along with this I will suggest some useful guidelines for future also that
    will handle your bowels very well in pace .
# chew your food thoroughly .
# balanced nutritious diet including green vegetables, whole grains , plenty
   of liquids & fiber , curd .
# avoid prolong fasting / overeating
# avoid sleeping for sometimes after meals 
# regular walking ,exercises help
# remain ambulatory , avoid 
stress episodes weakening gut
# quit 
smoking / alcohol / any abuse substances if using at all
# avoid oily / spicy / beverages / non vegetarian stuffs till possible
Hope this will definitely help you.
Thanks for using Health care magic .
Get well soon.
Regards .
