Help!!! I can't stay awake.

Chardonnay 💙💙
I just started a new job at a mortgage banking company, through an employment agency. They are super strict. They barely want you to even get up for a bathroom break during training. I even feel a way about taking off for my 13w appointment tomorrow. But my BIGGEST problem, is my fatigue! Sitting up looking at my facilitator as my eyes roll back in my head, reading material and I'm nodding off. I'm so afraid they will notice and let me go. I feel like I have narcolepsy. I haven't told them I was pregnant, and I don't necessarily plan to. I have been snacking to stay awake. But what else can I do to stay awake besides getting up and walking around. I no longer have the desire to drink coffee, the whole building smells like coffee and it stinks. I think hot tea makes it worse. No tea today. I'm going to try hot lemon juice. Any suggestions would help. I'm going to ask my doctor about it tomorrow. But I would like to know anything you all ladies might've done, if you had a similar situation.
