"i started 10mg 3 days ago oh my goodness the stomach pain and running to the bathroom! i feel as thou i am in labor with the pain! it starts after an hour taking the meds and lasts about 3 -4 hours! i take at 4am so i am not down all day long . thankfully, i don&#039;t have a job to go to because that wouldn&#039;t happen if i continued this medication.  i took half this morning at 6:30am overslept and oh wow still severe stomach pain as i write this running to the bathroom!  this is the only side effect i am having for now .  i am going to suffer thru this for i need some relief and have heard great things about this medication after you get used to it.  i also take 150mg wellbutrin and 15mg buspan 3x a day.  i hope all this works eventually"
