Does seroquel (quetiapine) xr feel the same as being on regular seroquel (quetiapine)? although both make me feel dreary and depressed

Quetiapine/seroquel: And quetiapine (seroquel) XR can both cause sedation and may cause fatigue. If you’re feeling dreary or having new mood symptoms, possibly from your meds, please discuss this with your prescriber. It may also be a new symptom of depression or other problem that's arisen, there's no way to know without evaluation to determine why you're feeling this way. Good luck!
