Hi Phoebe,
Ask your GP about gabapentin.
It's a wonder drug - off label use for sleep.
Works wonders for me and also seems to have a mild anti-depressant quality for me and many people.
Of course depends on your health situation / other meds etc.
but worth a try.
Most actual sleep meds are bad for getting addicted and have awful withdrawal.
If I don't sleep it all goes to hell very fast as then have no emotional control.
Hear you about the roller coaster - sounds like we were having bad days at the same time.
Where have you hiked in Idaho?
I'm from KEtchum/Sun Valley and grew up hiking and backpacking in the Sawtooths.
Thinking of going to Idaho for part of the summer - my whole family is there.
Good luck with new hiking buddy.
Thinking of you.
