Psychic Seizures - Diet?


I'm new to this forum and was diagnosed with epilepsy a few months ago after living with it for about 4 years. 

I have simple partial seizures, which I have narrowed down to "psychic seizures" in which stress is a high factor in starting them off. I am currently on Lamotrigine and I'm finding it okay so far.

I have very intense deja vu episodes and it's been very comforting to know that I'm not the only one experiencing these strange symptoms. 

I have had two seizures since being diagnosed, the last one being last week which happened whilst I was drifting off to sleep. It has made me feel tired, sluggish, weird and sensing that another may be on the way. 

My diet is not the best it could be at the moment, but I'm trying hard to change that. I read somewhere that too much sugar could trigger the seizures. Does anyone have anymore information on this. Or know what to avoid in food that may trigger episodes. Or simply, if food does not affect seizures at all. 

Any info at all would be great. 

Thanks for reading :)
