Is my journal grammar correct?

I'm going to start making a journal about my day with simple sentences about what I've done. Here's a sample of my first day:

-ฉันกินมาม่าแล้ว

-ฉันเดินแล้ว

-ฉันดูโทรทัศน์แล้ว

Am I putting 'แล้ว' in the right spot? I read it goes at the end of a sentence, but I also read it goes after the verb, so now I'm not sure. Thanks for any help. :)
