This procedure is not entirely successful but does make some difference in the levels. I am unable to break down phytanic acid, an acid which is common to many foods but has exceptionally high levels in any by-product of lamb or beef. The acid attacks the physical nerve responses of the body. I spent two years in rehabilitation after the initial diagnosis. If anyone asked me to smell anything I always took my cue from their voice intonations.
Taste is also a personal experience.
Whilst I can taste sweet, bitter, salty, I am unable to distinguish subtle flavours such as herbs and spices. I also enjoy going out to dinner and it is one of our favourite pastimes, trying new and different restaurants and cuisines. I have found the combined loss of vision and hearing to be the most difficult of all. It is often hard to convince other people that you can be both deaf and blind at the same time even if it is only a partial loss. It can be very stressful trying to participate within the general community because one needs BOTH senses to be able to function around a whole person.
