Tried meth 1st time 4 days ago and have used it last at 3am.How long for recovery + other questions?

I completely regret having ever tried this drug and am stopping immediately. Unfortunately since I first used recently, I’ve used it daily and hardly slept. I’ve drank a lot of water during this time and also taken some multivitamins each day.

Tuesday, first time trying it, i snorted it about 9 and then a little more later, no sleep.

Wednesday- went to work, never ate, smoked some and snorted some, ate a couple protein bars and some orange juice, slept 2 hours

Thursday – went to an appointment then slept 4 hours or so during the day, used again in the evening snort / smoke. got about 3 hours of sleep after taking some xanax. Decided I wanted to stop using after 1 more day, shoulda stopped right then.

Friday – went to work, came home, drank a protein shake, snorted / smoked several times up until 3am, no sleep.

Now, 11am saturday, cannot sleep still, chest feels tight and i cannot get comfortable trying to sleep, also experiencing the loss of interest in most normal enjoyable activities. I am about to drink another protein shake/vitamin and lotsa water (i have no appetite to eat something solid =/)

Without assistance of another substance, estimate when I will comedown and be able to sleep?

Estimate if I can get a hold of some xanax?

I estimate my total intake in the 4 days at about half a gram.

Should i anticipate several days of recovery or will a good 18-20 hours of sleep eliminate the physical symptoms?

Smoking weed made me less able to sleep the night i tried it so thats not an option for sleep, and read that alcohol can help but would rather avoid it.
also have an appointment monday for wisdom tooth removal consultation and they may remove them same day but I will reschedule if they cannot use local anesthesia as I’m afraid of general anesthesia. Will there be a problem with the local anesthesia, should I simply have the consultation and schedule the removal for a week later?
