‘While’ in this context would be better if it was qualified - a little while later/ a long while.later.

There is no comma needed after ‘bed’.

To me, ‘from buying food at a nearby convenience store’ and ‘after buying food at a nearby convenience store’ are both acceptable.
In my opinion, the nuances between the two could be as follows:
When you use from, your main engagement was shopping. If you use after you also had other things than shopping.
When you use from, you may have come back direct from shopping. If you use after, you, perhaps, did not come back straight after shopping.
