The Modern Household Encyclopedia includes this remedy for chloroform poisoning by inhalation:

If inhaled, give fresh air and keep the head down; massage in heart region; apply external heat. Artificial respiration may be needed. Call a physician as strychnine may be needed.

It also includes the following about strychnine poisoning:

If severe little can be done except call a doctor immediately. Antidote: very strong tea or tannic acid. Give emetic.

Instead of risking death by chloroform poisoning, you could try this less toxic option from the CWA Cookery Book, Tenth Edition:

Solution of common salt in water, followed by solution of soap and methylated spirits.
