Sueg,
the cramps and the twitches, yes. I get them almost everywhere, it's very annoying: legs, feet, hands, arms, my tongue (!), eyelids, and even my abs. Never heard about the hiccups, maybe someone else?? I'm sneezing all the time, dr said it's because of inflammation - never thought it could be lyme/bart related.
If you are drinking lemon water, it might be better te leave the lemon for now, it can make the twitching worse.
Are you taking magnesium? A lot of people get help from it when having twitches and cramps.
