Indigestion and Constipation. Months.

Over the years I built an habit of a black coffee and smock in the morning for the bowel movement. It's been 38 days now since I had a smoke or black coffee in the morning. I am drinking plenty of hot water and it is helping but the process is very time taking and I do not get everything out of my system in one go like I used to earlier. I feel like going to restroom twice or thrice a day and constipated all day, resulting in farts. I have also changed my diet, I am eating only vegetarian food and good amount of ghee in it. I am also eating good amount of fruits in a day. I am also running almost everyday. So I am doing everything I have read so far on internet but results are little slow, may be because of bad habits of years. I just wanted to consult a doctor also now and see what a doctor suggests. I have also tried Laghu ShankhPrakshalan kriya to clean your entire digestive system, might do once in 2-3 months.
