I'm kind of in the same boat as you. I'm almost 3 months in. The things that are really killer are the fatigue, irritability, and memory/concentration issues. Its like I am thinking of something but I can't pull the word I need out of my brain. Very foggy and forgetful. I just saw my derm on Friday, and we agreed to push through. But everyone is different and can tolerate different things. What is your dosage and have you talked to your derm about your side effects?
I am 3 months into my second course of Accutane and I am fed up with it to be honest.
So far my side-effects have been dryness of the whole body, fatigue, poor concentration/memory, irritable and moody and nightly nightmares
I really want to see it through but 3 more months seems so far away and I don't want to continue like this, what do you think?
Don't give up. Keep pushing through and you will get the results you want. I'm on my 4th course of isotretinoin currently and have trial and error'd some products I could recommend you in dealing with the side effects. Please see my page as I must have written a million entries with them and my journey by now . As for the mental side of things, try to keep active, go to the gym etc - 3 months is nothing in the grand scheme of things. You'll be glad you did it when completed.
Stay strong, feel free to drop me a message. Best of luck.
