I've started HRT and I'm on my third Evorel 50 patch. I've been struggling a bit - headaches, feeling sick and a bit jittery or very sleepy! I obviously can't talk it through with the GP until next week so I'm wondering if I should just take it off and start on a lower dose next month. Or can I cut the patch in half? I've read it's fine and I've read it's risky. The leaflet makes no reference to cutting it
