The variables that decide how a cross-border order goes are declaration wording, the destination country's import rules for prescription medicines,…

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. Import rules are jurisdiction-specific and this board keeps giving US-shaped answers to non-US questions. What is a personal-import allowance in one country is a controlled-import offence in another.

I spent a month blaming the drug for headaches and light-headedness that turned out to be salt and water, which is embarrassing and apparently common.

Helpful anti-nausea foods for hydration users:

• Ginger (tea, chews, supplements — all work)
• Peppermint (tea or oil capsules)
• Plain crackers or rice cakes
• Bananas (easy to digest, replenish potassium)
• Clear broth (hydration + sodium)
• Small amounts of protein (chicken breast, plain Greek yogurt)

Avoid: greasy foods, spicy foods, large meals, lying down after eating. Keep meals small and frequent — I do 5-6 mini meals/day.

Muscle cramps on hydration — anyone else? I was getting severe leg cramps at night, especially calves. Bloodwork showed my potassium was low.

GLP-1 agonists can cause electrolyte shifts due to reduced food intake and GI effects. Get your electrolytes checked and supplement accordingly. I take magnesium glycinate 400mg + potassium gluconate 99mg daily and cramps are gone.

Following on from hank_denver — and this may be the naive question:

Which of the variables in a cross-border order actually determine the outcome, and which are superstition?

OP back with an update, since a thread like this is useless without one.

Reporting back for the archive rather than for the thread: I did the narrow version of what was suggested, gave it the full interval, and it settled. Posting it because threads without a follow-up are half a thread.
