Sorc solo. BG1 any problem?

Ive done most of BG2 solo as sorc long long ago. Such a fun class to play so gonna make a new one soon, and this time do the whole saga.

Is there any issues running a lone mage in the first game and being weak like a kitten? Or is it just a matter about using invisibility and sleep alot?

Also, best race? Should be Elf?
