I would also recommend any sort of antidepressants you can get.
If something happens for which preps are needed people are going to be freaking out. Being able to calm them down and get them to sleep is going to be a gift beyond price.
That's why God gave us home-brew.

Negative on that unless they are already being prescribed. Typical antidepressants (SSRIs; SNRIs) would take weeks to show much therapeutic benefit, and any improvement in mood is going to occur only if the brain's neurochemistry is deficient in the manner that the drug is designed to treat. Basically, a typical non-clinically depressed person is only going to see the side effects. Even worse are the withdrawal aide effects that can occur with abrupt, unsupervised cessation; these have put people into the ER (which if it is running at all will be busy with more pressing conditions).
When something really bad happens you are supposed to be depressed, and maybe shocked and angry. This is a normal reaction to situational factors. Trying to drug yourself into some kind of anesthesia instead of coping as best you can is not a good idea.
Benedryl is an antihistamine which will aids in drowsiness at 50 mg or higher dosage; vitamin D3 in 10,000 units per day dosage, daily, is an excellent means to stave off depression and increase a sense of well-being; D3 also speeds recovery when injured
Personally, I'm going to stock up the ibuprofen, too, because it is an excellent anti-inflammatory and pain medication, though it is more easy to overdose than folks might think.
