I do that aswell , thing is I know exactly what my problem is but keep doing it , i get so cross with myself , every weekend I drink wine on a fri and sat night which I've saved syns for but then I get wine munchies and it all goes bad from there , sometimes I wake up sun morn and find lots empty crisp and choc packets and I feel awful and every Monday I think right that's it I'm not drinking this weekend but after a tough week at work I always end up in tesco buying wine i know it's my fault but don't know how to stop myself
