Been in a weird mood..

Went with my husband to a party for his friends... Usually I am hard into drinking liquor with them, but just wasn't feeling it the entire time of me drinking I just felt more and more sick (not puke sick just uneasy way). There was no way any of it was poison because it was seal and never opened... I just don't know, I been acting weird the last week also... Just kind of wanted some insight on why I was having that weird feeling..
