Learn Spanish (Latin America): Casi siempre me levanto temprano.

Adverbs of frequency like siempre (always) usually go right before the main verb. Notice that because this sentence has a reflexive pronoun (me), the phrase casi siempre goes before the pronoun, not between the pronoun and the verb.

Can I use casi with other frequency words from this lesson?

Yes! Casi means 'almost'. Just like you can say casi siempre (almost always), you can also say casi nunca (almost never).

Why is it me levanto instead of just levanto?

Levantarse is a reflexive verb, meaning you are performing the action on yourself. You need the pronoun me to show you are getting yourself up. If you just say levanto, it means you are lifting or raising something else, like a hand or a box.

The English translation says 'wake up', but I thought the verb for that was despertarse?

Good catch! Strictly speaking, despertarse means 'to wake up' (open your eyes) and levantarse means 'to get up' (physically get out of bed). However, in everyday conversation, people often use them interchangeably to mean starting their day.
