Allergic to Alcohol

You are aggressively allergic to alcohol. It could be physiological, it could be psychological, but either way the mere thought of consuming alcohol is repulsive and nauseating for you. If you consume alcohol, you suffer the poisoned condition and must make a constitution save (DC 10) or also suffer 1 level of exhaustion. The poisoned effects continues for a number of rounds equal to 1d4+1 per "drink" imbibed, with constitution saves happening at the end of each round and escalating by +1 each round to a maximum of 20. Every failed save beyond the first is 1/2 level of exhaustion, but round down to nearest whole number any time you need to assess how many levels of exhaustion you actually have.

FLAW. This is a flaw feat. At your DM's discretion, you may take this feat at level 1. If you do, you may also gain a feat, or increase two of ability scores by +1 (or one by +2).
