I am sorry you are having these problems with your sleep.
I am very doubtful that the problem has anything to do with AMN or Baclofen withdrawal. Thank you for detailing the drugs you are taking. I am wondering why you are taking these, and if they have been prescribed for you by a doctor.?
All drugs have the potential for side-effects and for problems caused by interaction with other drugs. As soon as you start taking multiple drugs as you are doing, you need to be careful and get good medical advice. Because I was concerned about this aspect, I started looking and found some useful information on drugs.com. This web site has a section which explains possible bad interactions between drugs.
If you go to drugs.com/drug-interactions... you will find a whole discussion on drug interactions between Celexa and trazodone, two of the drugs you are taking. The symptoms they describe here look very like the ones you are experiencing . They say these interactions can cause a rare but serious condition called the serotonin syndrome.
So it is really important for you URGENTLY to consult a doctor and explain these drugs you are taking. You could be doing yourself harm otherwise.
From the information I have found here I am pretty sure that what you are suffering from is due to these interactions and not from Baclofen withdrawal or AMN.
Please let me know how you get on, and PLEASE CONSULT A QUALIFIED DOCTOR AS SOON AS POSSIBLE.
