Not to be gross but...How do I get my bowels going regularly?

I had throat surgery on the 19th and due to complications with swelling ended up in ICU twice in the following week. I am now on the mend but my digestion is all messed up. I have not had any movement on my own since. On two occasions I have used a strong laxative just to get relief from the extreme bloating and back pain associated with the constipation. I am taking lots of digestive enzymes, fiber, detox teas and eating salads amd on a strict diet (no processed foods, wheat, sugar, dairy, legumes - strictly paleo). My stomach gurgles all night with gas and cant sleep well for it. Any suggestions?
