My doc switched me over to lexapro & told me to take 1/2 a tablet a day for 4 days, then 1 tablet a day after that. This is only my 3rd day on it, but I've felt pretty awful the last few days, and not sure if it's from that or not. I wake up in the mornings feeling sick to my stomach & that comes & goes throughout the day, just feeling kind of nauseous. Yesterday, I actually thought I was going to throw up, thankfully I didn't. I felt kind of 'in a fog' all day today, and couldn't seem to concentrate or think straight very well. I'm also MUCH more tired suddenly. I came home from work today & pretty much just passed out...we'd planned on going out to eat, but I just couldn't make myself get up again. Has anyone else experienced this? Could it be coincidence, or is it switching to lexapro...and if so, how long before the side effects go away? I just don't know how long I can handle this. I'm SO tired, but not sleeping well at night, and to top it all off, my rx for ambien ran out & the insurance company refuses to fill it for another week! Aack!! They say it's too soon, and 14 pills should last a month...and it's almost $100 to pay out of pocket, which I just can't do. So...I'm taking my klonopin at night with my lexapro to try to help me sleep, but the klonopin gives me bizarre, vivid dreams. I sleep though, so I guess I can't complain too much. Anyways, just wondered if anyone else had similar experiences. Thanks!
