I also suffer from this. Because of the nature of it(!) I can't remember how far back I've been having it, but I'm almost certain this started for me after glandular fever/ME symptoms began, as it would certainly fit with what my then partner thought were anxiety attacks, which never explained how they came out of nowhere and disappeared just as quickly.
For me, they will start with a tingling sensation/odour in my nose (like being hit on the nose!) Then a rushing sensation up my arms coupled with rising sensation in stomach and extreme nausea. I vomited once. Then I'll start recalling nonsensical dreamlike 'memories' for about 30 seconds, which I feel like I'm right on the verge of making sense of, and then it passes, and I'm left feeling exhausted. Some days the exhaustions so bad I'm wiped out on the sofa all day and time slips by without me realising. Other times it's so mild I hardly notice it. More often than not accompanied by mild-moderate migraines.
Mine usually occur for a few days each month, and it started to look like it was related to my cycle, but not always. I saw a good neurologist, negative EEG with sleep deprivation, hyperventilation and strobing, but she still didn't palm me off with anxiety and diagnosed TLE, wanting me to take lamotrigine. I declined but reading this has made me wonder whether I ought to try it:
In terms of treatment, anticonvulsant drugs can help TLE. Anticonvulsants have a seizure-suppressing effect. One commonly-prescribed anticonvulsant is Lamictal (lamotrigine), and this is also one of the drugs Dr Jay Goldstein would use for his ME/CFS patients. I bought some Lamictal online not so long ago, and I tried very low dose Lamictal myself, 12.5 mg daily, and it helped my ME/CFS a bit, but the benefits seemed to wear off after a few weeks.
Just wondering what the rationale is for using it in ME? One of the reasons I didn't want to take it was because I was told it'd make me feel tired and washed out (the other being SJS)!
Hip I loved your positive spin on TLE too, had never really looked at it like that but yes, I've always had a spiritual type personality. I read about the hyperreligiousity associated with TLE a couple of years back and it made me not trust whether it was 'me' or the Illness, so I dissociated myself from those interests...
I also have childhood memories of a fever, and feeling like my hands were blowing up and shrinking over and over again to a horrible delirious rhythm inside my head... I'm reminded of it every time I hear Comfortably Numb!
