You previously indicated you took ibogaine to treat your emotional issues. You suffered disastrous results.
Please, I recommend you seek the help of a qualified therapist. Sounds to me, those emotional issues are not only still festering - they are amplified. This alone can cause one to be tearful, ultra sensitive, out of control and yes - it can manifest itself in twitching, sleep deprivation, weight loss, weight gain, perceived weakness etc.
Get some perspective; you are researching a guy who porports to cure ALS - and you likely don't even have ALS. You're putting the cart before the horse. Stop focusing in ALS and start focusing on what's really troubling you. Inside.
Is your neuro consult thus week?
