I spent a week on Lexapro 5mg and am half-way through my first week upping it to 10mg/day. I'm struggling with constant fatigue, spaciness, and lack of motivation--not sleepy really, just like I want to be lying down doing nothing all day. I've had some sleepless nights, but it's not consistent. My biggest concern is that I've become pretty grouchy and feel like I can't pull myself out of my bad mood. I find myself getting irritated with small things--traffic, lines at the grocery store, and pretty much anything my wife does (even when she's trying to help me!). I'm feeling a little hopeless and would love to hear from others who experienced similar effects. Thank you!
