Ohh, my favorite topic.
My first antidepressant was escitalopram, I started taking it somewhere at the winter. Then I got spring flare-up. My psychiatrist at that time persuaded me to go to a psychiatric hospital. To do that, I needed first go to our main town psychiatrist (cuz mine wasn't living at the same place) so they will write me referral to hospital.
Towm psychiatrist didn't write it, instead she literally sat there, scratched her head while mumbling "What do I prescribe you..." and wrote receipts for amitriptyline and chlorprotixen at the same time, telling me to quit escitalopram. These didn't work.
At last summer, I got to another good psychiatrist, and she prescribed me venlafaxin. It worked a bit, then I witnessed death of my pet, got fall flare-up. She added teraligen. Didn't work. Switched to lamotrigine and added mirtazapin. It worked! Got spring flare-up... she switched gosages to 2 times bigger, added quetiapine, it worked and now she tells me to use it at flare-ups. At June, one event happened, got flare-up. I take now at day 225mg of venlafaxine, 200mg of lamotrigine, 30mg of mirtazapine. Except for venla it's almost maximum dosages per day. I should take quetiapine but I am just done with everything and will ctb.
She also gave me receipt for 25mg atarax, and for some time it worked. Then I got heavy breakdown and drank 3 pills, was a little dizzy, slept for around 3 hours and woke up good. Now it barely works. My psychiatrist thinks I have resistancy for antidepressants.
So... tl;dr: escitalopram, amytriptyline, chlorprotixen, venlafaxin, teraligen, lamotrigine, mirtazapine, quetiapine, atarax. They eventually just stop working for me.
