try some excedrin. try 2 maybe 3 at a time. i was up to 8 ibuprofin a day when i tried this. after a week or so mix it up. try excedrin one day and ibuprofin the next. something is clearly wrong so seek help if you have medical coverage.
maybe something to do with your eyes?
i use the rio 3200? i believe.
it's got 32mb's and i paid like$80.
i have no complaints, actually i like it very much.
it's very expensive if you plan to upgrade.
