Worsening seizures (while no increase in alcohol)

Doctors have been treating me since I was a toddler. My seizures have got more freqent and more severe over the last 5 years. I've been keeping a log of them, the build up to them and how I felt after. 5 years ago they were happening every 6 - 8 weeks and the great thing is that there was always a warning sign in the morning that it was going to be a day were I have a seizure. Also they were only partial seizures. 2 years ago they were happening every 4 weeks. One day I had a full seizure (my first full seizure in 20 years) and the neuro upped the Lamictal from 200mg x 2/day to 250mg x 2/day. Now they are happening every 3 weeks and the worst bit is that they happen out of the blue i.e. there is no warning that it's going to be a day of seizures. They have only been partial seizures over the last year. I'm reluctant to go to the neuro again at the moment because I'm working self-employed so can't afford to risk having medication changes that backfire and make things go from bad to worse. Before conceding that I need to let the Neuro try out different medicines, I was wondering whether it's work experimenting with giving up alcohol or whether it would be a waste of effort? Here's the pattern....: 5 years ago I was drinking 3 pints, 3 nights/week Today I'm typically drinking 2 pints Tuesday night and 3 pints Saturday night. Seizures have never happened while drinking, nor have they happened the day after. Strange that they are worse now than they were 5 years ago when I was drinking more often. Is it worth the time/effort of seeing whether giving up drinking would make a difference? Or are seizures a vicious circle where having 1 makes you more likely to have another, and that's why they've become more freqent and more severe? Thanks
