So,ya...for the last say 6 months or so,ive been getting two completely different kind of stools during the same bowel routine

-1st comes the formed light brown log...Moderate to large
-Then,a stim and about 5mins later comes a large,thick,heavy dark paste! I say paste cause thats whats its like,its not formed at all..and its so thick and heavy that if it doesnt hit the hole in the toilet and hits the edge above will sit there for several flushes before it finally slides in..

Im just curious if this is normal? It works will for me,because i know until i get that second drop that my business isnt done.The whole routine takes about 30-45mins every second morning..
