Hi everyone. I'm 11 months in losing my partner to cardiac arrest and having a mental breakdown with severe anxiety not only caused by grief but other things going on in my life, especially with my teenage son. Been prescribed Citalopram by the gp yesterday and was wide awake all night long after taking the first one. I don't normally sleep a lot but this was awful. Also have bad headache and feeling a bit shakey. I work full time as claims manager and not sure how I am to get through the next few weeks. Has anyone taken this medication and if so, has it helped? Was it bad to start with then improved? Thanks x
