I just took my first dose this morning and I DO NOT like how I feel already!

It is only 10mg but it seems like it hit me pretty fast - I would rather deal with my anxiety (which honestly isn't super horrible - mostly tighteness in chest, exhaustion and not sleep good)!

How long will this last in my system?

I do NOT want to take it again tomorrow if this is how I will feel. I will start a new job in a few weeks and I can not afford to blow this!

If I do not take my second dose tomorrow will it be out of my system. It hasn't built up in my system yet right?

I plan to call the doctor tomorrow (today is holiday).

Thanks for any help!!!
