I don't know much about the health-care system in Spain(waiting lists etc), but you can rest assured that when and if you see your doctor the first sentence from your lips should be what I have quoted above 'word for word' you will be bumped right up the list and probably be given a full examination straight away!
The whacky tobachey just increases the brains pleasure responses making mundane drool seem interesting.
Go to the doctor and tell him this, wear something nice like a giant hot-dog or something that compounds your nuttyness....joking aside all thats going to happen is you Doc. will prescribe you even stronger so called legal drugs which will probably do more damage, so you have a choice to make, grab the bull by the horns my Espanol friend or continue to chase your tail, there is no mid-ground just quit.
