I dunno if this is silly or not but I'm only on day 5 of taking these meds for anxiety,PTSD, and depression I was prescribed them to try out and see how it goes. 

The last 3 days I have been sleeping a LOT! Now I'm a heavy deep sleeper anyway but this is way extra I sleep through all my alarms and just have no interest in anything except my bed.

Is this normal? Has anyone else experienced this? 

I think its probably something else because I was told these don't kick in for at least 4 weeks and I won't see any positive long term changes until about 4 months in according to me GP. I just wanted to see if maybe the two are related.
