Medication side effects and managing lack of stimulation in everyday life

I've recently been prescribed with Vyvanse after being on Ritalin for a month. The effects have been amazing and I can finally focus at work and manage my emotions a bit better. However, I have noticed some side effects which have been of concern but has slowly subsided. One of which was an uncontrollably high libido that has since dropped down to below baseline levels then returned back to normal, if not a little higher. I've also noticed increased impulsivity which has led to making some decisions that I've later felt guilty about and regretted but hence moved on from that. Furthermore, I've been noticing increased irritability during periods of low levels of stimulation in everyday life and difficulty managing boredom. This has also led to some questionable decisions when paired with impulsivity.

My question is, how do I deal with periods of low stimulation and being comfortable with boredom? What are some of your experiences and some things you've found have helped?
