Cannabis withdrawl questions

Little bit of context before my questions: I (34m) used to live in a state where weed was legal and plentiful and now do not. I would usually smoke a joint or 2 on my day off and hit the pen after a day at work to wind down / help sleep. Probably been in this routine since COVID.

My stash has since depleted and thought "ya know it might not be bad to take a little break". For about 5 days now, I haven't smoked (done stretches like this before) but I've been having temp swings, extreme fever spikes, foggy brain, trouble sleeping, trouble eating.

I feel like these seem to be typical withdrawal symptoms and looked at some sites that give me matching symptoms to what I have been experiencing. I've ruled out illness because I don't have any cold symptoms.

Here are my questions to the internet: 1. Most sources I read said that by 3 weeks, everything should pass, is there anything I can do to expedite that process? Working out more, relentlessly chugging lots of water, etc. 2. Is it better to wear my way off instead of going cold turkey? I did hit my pen last night just to try and work up my appetite which worked and I felt better overall, but it was about the same time my ibuprofen would have been kicking in 3. Have any of you experienced this before and what werr your thoughts when it did? 4. Is this even weed withdrawal? I haven't gone to the DRs to get any official tests done for my health of other possible explanations.

Thanks in advance, wish me luck!
