Percocet withdrawal Question please answer..?

Ok, I have been on percocet for about 6 years already i was using 10mg 5mg 7.5 mg i would even take a 30mg and cut it in half and take half more than once I have been on oxy 40's too not all at once but including durgesic patches over the course of 5 years I stopped I havent taken anything in over 4 weeks I have no insomnia, no shakes or chills I have diarrhea it gets semi better than sometimes goes back to diarrhea is it due to the withdrawal stage maybe my system is trying to transition? When I take them or take 1 perc my bowel movements are basically back to normal and no diarrhea is my digestive system messed up from the pills and always being on them? Is it gonna take a couple months for the diarrhea to go away i have not been on immodium or no anti diarrhea medications should i try for one of those? Its not always pure diarrhea either sometimes i have better days with using the bathroom its like it gets ok then it gets a lil messed up then kinda normal
