Brief Answer:
Read below.

Detailed Answer:
I read your question carefully and I understand your concern.

I do not know of any drug called amnion, could it be a misspelling, could it be Ambien perhaps?
Anyway your description of falling asleep at inappropriate moments corresponds to a condition called narcolepsy which manifests with such sleep attacks and excessive daytime sleepiness.
Now the condition must be differentiated by some other possible causes like sleep apnea (episodes of interrupted breathing during night, with low quality sleep and excessive daytime sleepiness - common in overweight people) or low thyroid function. So some testing is necessary starting with a sleep study, an exam where electrodes are placed on your scalp to record brain activity during sleep.
As for who to go to, the best equipped are doctors with a subspecialty in sleep medicine (commonly with Neurology, Internal medicine or respiratory care as primary specialty), often in the setting of a sleep clinic. If you need suggestions in your area, I could mention the IU Health Saxony Hospital or the Saint XXXXXXX Sleep Disorders Centers. Below can see a couple of links for contact:
