Husband started Effexor about 3 weeks ago for MDD and PTSD. He seems super forgetful (forgot to take his medication one day, forgot to take our daughter to an appointment, and then forgot she had an mri) and looks like a zombie. He asked for a divorce less than 48 hours after starting it and has stuck to it. Says he’s never thought so clearly without being angry or spiraling.

What are the chances that these things are just him and he really is just this way or is it the medication?
