Ibs, green poop, acidity. Part of ibs.

Hi, I am 42. I have been suffering from loose stools on and off for the last 2 weeks. I have IBS. The stools have been green and semi solid or loose. The frequency is twice or thrice and mostly right after breakfast. I took nizonide twice a day for 5 days.  I'm also on sompraz d, librax in the night and unienzyme after meals.  Post 2 weeks, I still have diarrhea on and off and the poop is still green.  My nizonide dose got done last night. I will have the bitter taste in mouth today as well.   Earlier symptoms also included stomach cramps etc.  Currently it's gas, Acidity,  green loose stools two or three times a day. I'm anxious that this will not resolve and I'm getting worked up.  My ultrasound and gen blood tests were normal 2 months back.  This has now been there for 2 weeks.  Will this go away soon.  Will the poops color turn normal.. is this something serious.. is this part of ibs.. please suggest and advice so I can wait this out without anxiety.  Thank you.
