Any Mods/ENBs active? Disable them -> reload.
Could you test if this command in the console freezes anyway?
Then reload and try throw away some arrows before drinking the potion.
Does it freeze again?
If it's still freezing attach a save as .rar or .zip:
Savegames can be fund here:
documents\mygames\skyrim\saves
one savegame consists of two files: one .skse and one .ess
Thanks
note to self:
Same problem in the german forum
