I have tried both and found out the same thing , I am seriously allergic to all of them , AD have put me in ICU twice , the first time was for 6 months with cascade multiple organ failure. SSRI, SSNRI ,TRI, all was much the same, the one I am not allergic to Mirtazapine(Remeron). I am a Doctors worst nightmare, I am allergic to so many drugs , when something is wrong with me they can't play polypharmacy until something sticks, they have to actually put some thought into it and consult with many other doctors to find something relatively "safe".
