A few days ago i started taking Prozac, I am taking 10mg for seven days, then switching to 20mg a day. I noticed that my eyes feet heavy, i feel almost hazy. and my tremors are worse, but i do feel calm for most of the day. The problem is though that as evening comes around I start to feel edgy, irritable and a bit high-strung again and by 8 or 9 o'clock I'm just "meh"... could it be the prozac? or am I just thinking too much about it?
