Hi Are there any experts/those with experience who can explain the difference in effect between alternative HRT patches? The reason I'm asking is that Estradot supplies ran dry, so my prescription was replaced with Estrderm. It's the exact same disrase but I think I felt better on the latter. Wondering if it's this or just getting longer sleeps (in major lockdown where I am) Have option to return to Estradot now (more user friendly) & not sure what to do. Chemist says only difference is in their mode of delivery (?) Thoughts?
