Lifestyle and meds and the possibility of intermittent use

Hi, About a year and a half ago I developed psoriasis and it covered my body, I would say upwards of 80%. The doctor's prescribed every ointment and creme under the sun to no avail because they couldn't pinpoint a diagnosis. Eventually they sent me to a dermatologist who was exceptional and put me on cyclosporine which worked wonders, I was so pleased. However, I have now come to the point when I have to come off of it and they're suggesting I go onto methotrexate. I know that keeping my skin clear, healthy and free of pain is the most important thing but I got down after my appointment because of the potential side effects and lifestyle changes I would need to make. I will see whether the side effects occur before worrying too much on that, but having to go almost t-total on alcohol is a concern. This is a frequent part of my social life, I am not talking about big binges all the time, just wine with meals, pints after work, G&T in the bath etc. but also for big events such as Birthday nights out or hen/stag dos now and then. If needed of course I will make the required adjustments, stopping the casual pints and glasses of red wouldn't be too much of a struggle but I was wondering if anyone had some advice or experiences they'd could share. My consultation talked about having intermittent courses of drugs maybe having a three month brake from cyclosporine and then back on or going on methotrexate but then switching to cyclosporine again. Though this would be down to the consultant. Has anyone else done this? If so did you have a flare up as soon as you came off meds? Sorry for the long post, and if you read it all I thank you, sincerely. Looking forward to hopefully getting some responses soon. :) L
