in the begining after a couple of months after the initial viral infections i use to plod along at about 95% (feel abit brain fogged)for a few days then i would have a few nights where i would get alot of pain down my lower legs, especially at night and this interrupted my sleep alot, my sleep wasnt the best even without the leg pain, then i would crash and sleep all the time for about 2-3 daysI actually enjoyed these times because i could sleep well drug free and for some reason had no aches and pains), then i would sort of recover back to 95% and slowly deterioate again in this sort of cycle pattern. This kept happening for a year or 2 then the cycle just stopped and i started function all the time at alot lower level maybe 80-85% with these 1-3 day crashes of just sleeping. i got to the stage of functioning at about 65% with lots of sleep problems, aches and pains etc until i started antivirals famvir approx 2 years ago, now feeling alot better, probably functioning in that 80% range. brain fog isnt as bad these days, sleep well with medication and im able to work full time but knackered at the end of the week actually probably after 2 days but im able to soldier through and rest up on my days off.
the way it initially started was strange, i was able to predict when i was going to crash, after those few nights of leg pains i would tell my wife im sleeping for the next couple of days, dont expect much from me till i wake up. it seemed strange, now i cant predict anything lol, but im functioning alot better with good sleep treatment with the av's.
