I am also on Tramadol. I am suppose to take 100mg 3 times a day but I don't always take that. I usually take it twice a day. I have gone to once a day at times and don't seem to have any symptoms when I do that. I also KNOW that it works for the pain.
You need to talk to your doctor to see if she has any suggestions what to replace the tramadol with if she does not want to have you take it. I hope you make out ok!
