working at night once the stims have worn off

In this career, it’s pretty typical to have to do extra work at home at night. While on the job market, it’s atypical NOT to have to work from home at night after working a full day. Taking work home has always been difficult for me for the usual range of predictable reasons, and I generally avoid doing it as much as possible.

It’s now entirely necessary that I work productively during the evening hours. Thus far it’s not going extremely well, probably mostly due to the fact that my afternoon dose of IR ritalin has fully worn off by the time I’ve eaten dinner and am ready to start working again.  I’m toying with the idea about talking to my doc about a lower 4th dose of ritalin on the days I need to work into the evening. In the past, however, she’s been less supportive of this because of sleep concerns (i.e., I need to get sleep and don’t perform up to par if it’s disrupted or reduced).
If you are able to work at home at night, how do you do it?

Perhaps more importantly, are you medicated while you work in the evening? If yes, can you then sleep at night once you’ve stopped working?
