My doctor just prescribed me Citalopram (CeleXA) for my anxiety and Lorazepam (Ativan) for sleeping. I took both of them last night at the same time and i went to be. All night long i was up and down. I could not stay asleep for nothing. I couldnt get comfortable so i keeped moving to. This is the first time this has happen so im wondering is this could be a side effect of one of them or a combination of both? The lorazepam is suppose to help me sleep but last night was the worse i have ever slept.
