He is taking methamphetamine
. It is an stimulant drug and it causes intense euphoria. When taken for long time it may cause depressive symptoms. Also its high doses are known to cause precipitation of acute attack of Psychosis
. He has been normal and then suddenly you notched that he has started sleeping excessively, he has somatic complaints of dizziness
, blurring etc, low mood and he usually remain on bed. It is most likely some form of depressive episode. I would advise him to stop taking meth completely. He should be taken to a Psychiatrist
for expert evaluation for any withdrawal syndrome or depressive symptoms. Medicines of SSRI, SNRI
group are very effective in these symptoms.
