If the dose requires that a total of 40 mg be given, then you take the ratio of the stock bottle (mg/mL) and solve for the total amount of mL that are needed by multiplying the amount of mL required (x):

Multiply by 5 on both sides to give:

Then solve for x:

Another, possibly quicker, way to solve would be to set up a proportion - one side the stock bottle ratio, and the other side the dosage requirements:

Cross multiply and you get:

And you would solve this the same way as above.
So
the patient should receive 9.091 mL of secobarbitol.

Well, I won't do your essay for you, but I can help outline some stuff you can change which will improve your health. Then, I'll leave it to you to explain <em>how </em>it does so! =)
So, I can't say these specifically apply to you, so I'll just make some generalised changes you can make.
<em>* begin working out</em>
<em>* eat healthier and nutritious food</em>
<em>* begin meditating </em>
<em>* cut out addictive tendencies (video games, etc)</em>
<em>* learn to love yourself (loving yourself is a key to confidence and self-forgiveness, which leads to better mental health)</em>
<em>* work on proper and consistent hygiene </em>
Hopefully, this helps! =)
