“Cam I operate machinery on my medication?”

The mirtazapine and pregabalin both have the risk of causing drowsiness and altered mental function. If you know that the medications don't cause any problems for you and don't cause you to be drowsy, then it should be ok to operate a forklift at work.

Hello Sir, 

Sometimes people are not aware that in some states including, FL psychologists are not allowed to prescribe medicines. So it won't be ethical or legal for me to give you any advice regarding your medication and whether they would impair your performance on a machinery. Have your Dr. and your Psychiatrist write a letter to your employer about the advice they have given you regarding this issue. May be that will help. 
Take care and be safe.

Well, this is a good argument for natural healing and a bad argument for pharmaceuticals. Maybe you can draw up a document taking responsibility for your safety as a forklift driver. I think you have to get off the medication, though. The body is designed to do natural healing, but the pharmaceutical industry is making a killing selling medications that numb out our feelings. Our feelings are there to help us heal. We have to work with them with bravery and courage. We need to go into our feelings and let them have their way with us: feel, cry, feel, cry, recall, rage, recall and cry, until we finish processing what is stuck that never got out. Now, if you have anxiety and depression all your life or as an underlying threat when things go wrong, it's probably because the first years of your life you were insecurely attached. If so, you need to get in touch with the feelings you had as an infant. I know that's a tall order, but you can allow yourself to acknowledge that you were a tiny baby and got left for a reason you couldn't yet understand (like Mommy has to earn a living). You have to sort of reason with yourself and let yourself know that those dark and anxious feelings are those of a little child, who believed he was worthless, because he was always being left. You can now correct that misinformation. You now know that Mommy going to work did not mean you were worthless to her and easy to leave. But, for argument's sake, let's say Mom was a worthless mom, it is still no reflection on you. Let's say you have a wife who leaves. It triggers the ancient feelings. You can grieve and then figure out how to choose better or do better next time. Let every failure be an opportunity to grow and learn. The way up is adapting. I doubt this pep-talk will work, because it's an attempt to represent a year's worth of therapy. But, that's the skeleton of the theory: You reprogram that baby within. Good luck.

Get letters of validation from your psychiatrist and medical doctor substantiating the medication and its benefits and side effects. Have them note your reactions since you have been on the medications for some time now. With this evidence, your employer should be more reasonable.
