... along with 15 mg of mirtazapine & 20 mg of paroxetine, to help with depression, anxiety and insomnia. My problem is that these medications are making me continually tired and extremely sleepy during the day. Is it possible that I just need to get used to these medications for the extreme fatigue to go away? I've been taking them for almost 2 months now. Any help you can offer is greatly appreciated. :)
