It might be worth changing practices gai, see a new GP. If you really are gonna go for it this time, a fresh face to discuss things with could be benficial. Failing that, speak to your own GP about possible referral to any addiction clinics, or even call NHS 24 for advice or perhaps visit their website, there are a myriad of links to organisations who could maybe help. Failing that, it's buy your own and DIY. But it really is benficial to be under med supervision if it doesn't intrude to much on your day to day life. I've been there with the Cods before, and I find it a great help to find something new to do to help replace the "boredom" of not taking them or something else. That's harder than it sounds though. But you seem really determined this time, this could be time you knock it on the head for good. I'm here if you want to bounce any ideas off me as others are also.
