Grid full except where stuck in BRHC:
33a More than one young salmon abandoning lake shudders with fear once (6) ??ISES
35a Develop work on one's own for Australian surgeon (5) ?AT?H
38a German weak from marijuana got on well in America (4) ???E
45a Woman's deserted former groom (7) HER????
I suspect 45a has no definition, the others may have misprints in their definitions.
Gentle hints to get me moving again appreciated
