Hi im new to this site just reading your post and yes my taste changed i couldnt eat chocolate milk ketchup for five years it was all bitter. But am now starting to enjoy it after six years still cant drink coffee . Same here with specialist they think im putting it al on as all my test results were within mormal range . I have to be careful with excercise too as it can trigger bad headaches . Do you have any trouble with noises like being in a restaurant multipleconversations . It has left me from doing anything social .. am trying to find some good ear plugs .. i hope you get your medication sorted .
