At the very least you should get back the price of your materials. Most say two or three times the cost of materials, depending on what the economy will take.

Cholinesterase inhibitors boost ACh levels not only at the neuromuscular junction but also in the autonomic nervous system (which controls involuntary bodily functions). Sometimes the drugs can cause diarrhea, abdominal cramps and/or excessive saliva. To minimize these side effects, your physician might lower the dose of cholinesterase inhibitors or prescribe atropine, which blocks the ACh receptors on nerve cells.
