How long did you leave it before increasing bupropion/wellbutrin dose?

Been on 150mg bupropion extended release for about a week.

First few days I was waking up throughout the night, been using a sedative since then so thats subsided.

However I'm still a long way off energised/motivated unless I take stimulant meds.

I know antidepressants take time but generally this is meant to be quicker.

When did you increase? or notice improvements etc?
