3rd day on Lexapro with xanax and i cant Sleep i keep waking up every 1-2 hours for the past 2days now. Idk if its the xanax and lexapro but ive been on it before and this has never happened. Iam getting Hot all over my Body my heart is racing. Well iam checking my pulse and it feels Fine!!! So what the??!! Am i freaking it in my Head?!! Jesus this feeling is so scary its making me nauseous. US time its 3:44AM i cannot sleep iam scared and getting shaky. What could this be? Ive been on lexapro before with Klonopin but not with xanax. And this never happened before iam really scared guys. What if meds arent working or will never work? Ugh this feeling is so nauseating.
