I am a 19 years old male suffering from Auto-Immune Pancreatitis for the past five years. I took wysolone for two years and now take Creon 10,000 enzyme caps once a day only. Now there are no symptoms but only the immunoglobin level spikes at times. I fail to fall asleep till 3 am and wake up before 11 am, which makes me dull and lethargic. I also experience lots of fatigue throughout the day. How can I get rid of my sleep disturbance? I also have a hydrocoele-hernia surgery scheduled next month.
