Please contact your pdoc for help with meds.
I am concerned that downing a pot of coffee may only make you jittery and unable to sleep. You could try a cup of coffee if you have an okay reaction to coffee/caffeine.
I am tending to think your current state may not be helped much by any stimulant. Yet, there again, please talk to your pdoc.
If you are in school, you can ask for accommodations for your illness. Others here know more about this. I hope they will come along and comment. ( Edit: Blue_Bird and I were writing at the same time. )
Wednesday will come quickly, as you know. I hope you can get some help soon.
Please let us know how you are doing?
I am so sorry you are suffering.
