narcolepsy
"I've just switched from Modafinil to Armodafinil. I take twice a day dividing the 150 mg tablet into 2 parts with full meal. With Modafinil I had eye-irritation. It wasn't serious, but good enough to make me worried cause I already have glaucoma. The eye irritation reduced as I divided my dosage of 200 mg Modafinil into 2 times with a full meal. Though it may reduce the effectiveness, but the side-effect alleviation was more prominent. This prompted me to take Armodafinil cause I thought I may reduce the dosage further. Hence started with Armodafinil 150 mg and I think the plan has really worked out. The eye irritation effect is virtually non-existent! Still it's early days to comment on other properties, but I will as they become evident.."
