First seizure and would like your advice

Hi Everyone, I had my first seizure on the 25/5/2017 (approx. 2.5 months ago), I'm 28 years old and have never had anything like this before. Since my seizure I have had CT, MRI and EEG tests. The CT and MRI have come back normal, but the EEG did show "a couple of bursts of spike and wave activity, in the front right of my brain. Leading up to my seizure I was under a lot of stress at work and as a result I was working 14 hour days (without having any breaks), missing meals and not sleeping very well (typically 5 hours a day). This sleep and work pattern lasted for approximately 6 months (certainly no less). During this 6 month period I had also started drinking quite heavily (for me), I was drinking approximately a bottle of red wine a night. The weekend before my seizure I had also spent 3 days in full sun (temp approx. mid 20’s, I live in the UK) gardening, this did give me heat stroke the day before my seizure. The day before the seizure I ate 3 meals at appropriate times and had 2 pints of cider and a bottle of red wine, throughout the course of the day (all alcohol was consumed during or after a meal). Luckily when I had my seizure a friend was with me. Before the seizure I had a really bad headache (the worst I’ve ever had). My friend said that my arm dropped to my side (we were sat eating breakfast at the time) I then fell to the floor and started convulsing. I was not conscious throughout and he said I stopped breathing and turned blue. He thinks the seizure lasted 2-5 minutes. I bit my tongue and dislocated my shoulder but didn’t wet myself. I was also instantly fully conscious, able to answer where I was, how old I am, I didn’t feel tired or disorientated etc. and the headache had gone completely. Since having my seizure I’ve not had any alcohol, I’ve talked to my boss so that my hours and work load are managed better, I’m getting regular exercise and I’m making sure I eat well. I’ve not had another headache or seizure since. As a result of my EEG the neurology consultant I saw has suggested I start taking Lamotrigine, gradually building to a maintenance dose of 150mg per day. I would like to get your thoughts as I’m not very keen to starting medication that I will be reliant on for the rest of my life, but equally want to get back to a normal life (I’m currently banned from driving for 12months). I accept I’m probably predisposed to have seizures given the EEG results. But my thoughts are if I don’t take the medicine and make sure I keep on top of the possible stimulus (stress, lack of sleep, food etc) and don’t have another seizure in the next 12 months I may be able to control it without the intervention of medicine, what are your thoughts and suggestions? Thank you for your time
