Avoiding Alcohol Psoriasis Test

I'm 33 years old and have suffered from moderate Psoriasis since I was 16, like most, it comes and goes but for the past 2 years my scalp has been terrible and the psorisais on my body has gradually worsened. I do get psorisias on my forehead as well - this seems to appear and dissappear on a weekly cycle, like clockwork. There are currenlty no creams that are doing anything to shift it, Ive tried them all... I have tried cutting out dairy for a month - no change, the same with Gluten. So I am now trying alcohol - I have been a fairly heavy drinker since a young age, I drink at least once a week and have done since I left school. I'd estimate i average anywhere between 25-50 units a week. This is generally social drinking, whilst watching the football or out with the guys from work and I mainly drink lager. As a bit of an experiment, I'm gonna avoid alcohol for the next month and see if it makes any difference to my condition. I'm currently 7 days inand visually there is no change although I have notice some change in the texture of my affected skin. I will update this post with any changes, Fingers crossed it has the desired effect.
