We're always pleased to hear your story - and what works best to help you get through an episode.

Triggers

Triggers vary but episodes can be brought on by a combination of one or more of the following: emotional stress or anxiety, intense excitement, lack of sleep or physical exhaustion, alcohol, menstrual cycle, some infections, or, in some people, certain foods such as chocolate, cheese (similar to migraine triggers). Doctors may question the use of marijuana as a possible cause of the episode, or suggest that the episode may be cannabinoid hyperemesis syndrome (CHS), but many people find small amounts are helpful as a relaxant.

In order to find out possible triggers for your episodes it will help to keep a journal where you note things like moods, consumption of alcohol, use of any recreational substances, tiredness, food eaten, proximity to female cycle, together with timing and duration of episodes to find out whether there is a pattern.

It may well be that an episode follows a certain combimation of triggers, or maybe just a single one. The more you know the better you should be able to control the number of episodes. By knowing your triggers you have the opportunity to either avoid them, or take preventative measures beforehand if it is unavoidable.

If necessary, follow this up with what you have previously done to; abort an episode, or treat an episode enough to avoid hospitalisation, or treatment within hospital if this was the outcome.

In the chart below the term P.O. indicates orally (by mouth); S-L is sublingual (under the tongue); treatment could also be by suppository.
