"i&#039;ve been taking 10mg of citalopram everyday now for 7 days and then had to up it to 20mg after that. have never felt so rough! those first 7 days were hell for me, really bad headaches sickness and very bad depression that felt worse than what i had to begin with! i hadn&#039;t been able to eat anything either 4 or 5 days into it, but i tell you now the first day i took the 20mg start of week 2 absolute different story. i&#039;m like a different person. please stick the first week out as that was the worst for me it does get better i promise. stick it out i nearly didn&#039;t but so glad i did now! i feel brilliant now. these tablets do work but give your body time to accept them and you&#039;ll reap the benefits. be strong and stick it out. tomorrow is another day :)"
