I was taking duloxetine with mirtazapine for OCD/some PTSD as well as depression. According to my psychiatrist, treating the obsession/compulsions required a really high dose of duloxetine so I got up to 150mg with 15mg of mirtazapine daily. Ultimately I wasn't tolerating some of the side effects - sweating, racing heart, etc - so we agreed to try switching to Luvox. I then took 120 mg for two weeks, 60 mg to two weeks, then completely off. During that time, I moved up to 200 mg. This was started in August, roughly six weeks ago. Mentally, I'm okay - mild to sometimes moderate depression but nothing I can't handle. My issue is the fatigue. I'm sleeping fine, but I feel so drowsy during the day and I can barely focus or motivate myself to absolutely work. I can barely focus for 5 minutes straight on work. The feelings are similar to withdrawing from coffee while being really burnt out. It would make sense to me that the reason I'm feeling this way is because of the lack of norepinephrine in my body - have other people had similar feelings/is this normal? And if so, how do people manage the fatigue?
