"my sleep habits are horrendous. I’ve always struggled with routine due to the ADD. I’m on the base dose of my meds (Vyvanse, 30mg) and I’m going to ask my doctor to up it to the recommended dose (50mg) and see if that helps."
I was dxed with ADD 20 years ago in my 40's. my sleep habits were horrendous as well but not for lack of trying. no doctor ever said so, but it's clear to me that my sleep habits were horrendous because of my apnea and plm.
in retrospect (like looking at the comments on my school report cards) it's clear I had ADD in childhood. also in retrospect I am convinced I had apnea from childhood as well (memories and witness reports as I started sharing bedrooms and beds in my late teens). I believe apnea/sleep deprivation at least exacerbated if not caused my ADD. I think my ADD symptoms are much reduced as my apnea and plm treatment progress.
I'm not sure if Vyvanse is a stimulant but I took a lot of generic adderall and modafinil before cpap. after a year or so of lousy pap treatment I gave up them up. I needed them to get through the day but felt I wasn't giving pap a fighting chance insofar as stimulants are antithetical to sleep. in time, my apnea and plm treatment has improved, not as much as I want/need, but enough that my need for stimulants is largely diminished.
