One month ago i had surgery to remove the majority of my pancreas and all of my spleen. I was put on tramadol 50mg to have 6 tablets each day (morning, lunch and evening). After 2 weeks of taking them, when i was discharged from hospital i decided to taper it down to 3 tablets each day. I just finished all my tablets 3 days ago. Since stopping the tablets i have not been able to sleep at all in the night, which is driving me mad as normally i fall asleep within 5 minutes of hitting the pillow. I have also got terrible headaches and my stomach is quite unsettled. I dont know what to do. I saw my gp this morning and i suggested this may be related to stopping the tablets but wasnt really given any helpful advice What can I do to stop headaches, stomach upset and insomnia after stopping tramadol?
