Staying awake on melatonin?

I woke up a little while ago and took some melatonin to fall back asleep but was still restless so I decided I would just start my day. Now the melatonin I have does say to take it an hour before bed, and it hasn’t been quite that long yet, but I really just don’t feel like continuing trying to sleep rn. I’m definitely feeling affected by it (or maybe just from having not gotten a full night sleep or from getting really high before bed last night) cuz I just typed the typed the entire rest of the post up til this in the title and was trying to post it and was getting really confused. If it’s the melatonin, will this effect my day at all? How can I more fully wake up if it will effect my day considering that I dont drink caffeine?
