excessive sleepiness for a while

[simonsleep]

long story short.

im 31 male 5'10" 220lbs.
at 23, had a mononucleosis. left me with acoufen and lactose intolerance.
at 24, had panic attack disorder, very bad.
at 25, start feeling asleep all the time during day. take nap every afternoon (never stopped since).
been followed by physician, psychiatrist.
tried several anti depressant, nothing worked.
Clonazepam bid .5 controlled anxiety.
after 5 years, stoped clonazepam, took me a year and a half to do it (switching to diazepam...)

a year after that, (no more anxiety, no depression, no more clonazepam)
been on modafinil 300mg (more mg gave me too much problems.) for a year. barely helped.
tried ritalin lately, brought back anxiety at 60mg sr. too bad cause i was doing a lot better.

now i had to go back to clonazepam to stop nightime panick attack and i'm back to starting point.
sleepiness.

i have pass all blood test, complete sleep test (2 polysomnography with latency at a year interval) and
everything is fine.

basically, it seems i need a cns stimulant, but they trigger panic attack.

i cant say im depressed but im tired of being tired. i cant work or have a normal live.

i need help.
thanks,

Simon
