@candle je vais bien aussi, merci !
je n'aime pas le café, moi je préfère le thé ;;
(here you were using the verb tense "Participe Passé", so you need to use "j'ai BU", the past participle of "boire") (past tenses in French are horrible, so it's a good start !)

@candle @Dalmaty "i drank" => "j'ai bu"

("je buvais" is a different past form, you'd use it to make the action the background scene of something else happening for example. Not here.)

@Louvelune @Dalmaty can you give an example in english of past tense drinking in the background? duo lingo also mentioned it but i dind't really get it

@candle @Dalmaty @Louvelune I was drinking?

@Hiraelle @Louvelune @Dalmaty ohhh that is a very simple and clear example, thanks!

@Hiraelle @Dalmaty @candle It's only one of the possible English forms, though.

If you were saying "When I was young, I would go out, drink at bars..." => You'd use the French imperfect too: "Quand j'étais jeune, je sortais, j'allais boire au bistro..."

@candle @Dalmaty It's like "I was drinking my coffee, and the phone rang" => "Je buvais mon café, et le téléphone a sonné"

We call this function of the tense "descriptive imperfect": you're painting the scenery, not telling a story of events. (in that particular verb, the whole point is to mix it up with the other past tenses for the actions)
