Brain zaps and RLS?

Recently used K on a nightly basis. Nothing crazy maybe couple lines (much less than 0.5 g per night) for a maybe 8-9 nights. Before that not a lot use or experience. Last couple nights have experienced disturbed sleep, weird dreams and what i’d describe as brain zaps and what I’d assume is RLS. Also weird sensations in my lower abdomen and pelvic region. Have read about ketamine bladder and immediately became concerned. Have also been using snow and drinking too.

Realize and recognize one should slow down and take breaks, but if one stops/slows down, what should one expect? Felt this weird buzzing in my head when i’ve been trying to sleep. Should also note that I experience most substances as stimulants in low dosages which upon reading i have determined is probably an uncommon genetic derived response. Thoughts?
