Hi, I started this month BC tri- sprintec, I don't know if this could be related to BC, but it seems like I can't sleep during night. Im 32, But I have energy during day. Also what is really weird I feel dizzy and off balance, it wakes me up in the middle of the night. My heart is beating fast. What is it? I don't drink coffee before bed. Very strange. Is it hormones related?
