I was sick in bed with a headache and nausea almost all day (long) yesterday.
be sick in bedは「病気で寝ている」という意味の慣用句です。sickの代わりにillを使っても良いでしょう。
nauseaは「吐き気、むかつき」です。他の言い方として"the heaves" "gagging(嫌な味や匂いなどでの)" "stomach upset(消化不良による)"などがありますが、これらは会話的な表現になります。
almost all day (long)は「ほとんど一日中」で、longはなくても良いです。他にも、"for most of the day"や"almost round the clock"という言い方もあります。
