From the other side of the consultation, briefly.
Dizziness and cardiovascular risk: I was lightheaded for the first 2 weeks. Root cause was a combination of reduced caloric intake and mild dehydration.
Fix: minimum 80-100oz water daily, don't skip meals even if you're not hungry (eat small protein-rich snacks), and stand up slowly from sitting/lying positions. Also check your blood pressure — GLP-1-induced weight loss can make BP meds too strong, requiring dose reduction.

Adding a me-too, because a thread of one person's experience is not much use.

I understand the skepticism — we've all seen "miracle" weight loss solutions come and go. But consider what makes GLP-1 agonists different:
- Phase 3 RCTs with thousands of participants (not 20-person pilot studies)
- Published in NEJM, JAMA, Lancet (not press releases)
- Replicated across multiple independent research groups
- Proven cardiovascular and renal benefits beyond weight loss
- Biological mechanism fully characterized at the receptor level
This isn't a fad — it's a new drug class supported by the highest level of clinical evidence. The comparison to past fads is understandable but inappropriate.

View ResultsOne concrete data point for the thread. For anyone assembling their own picture: Tmax is one to three days, terminal half-life about 165 to 170 hours, steady state at four to five weeks, and subcutaneous bioavailability near 89%. Those four numbers explain most of the questions people ask about timing.
A narrower follow-up, since the general answer is now clear:
What the dose-response curve actually looks like above 1.7mg, because the trial means hide how few people account for the extra loss?
