I tried to get the study re-started on my own but a lab of 1 is not sustainable. so in April 2022 Michael started, and recruitment took off. after just a few months in the lab, Michael said he had a hypothesis he was interested in testing:

does neuromodulation to dlPFC only reduce craving and withdrawal because it's improving underlying mood problems (like anxiety, which often heightens during withdrawal)? or is it having a unique effect on craving (separate from well-known effects on mood)?
