Hi Joann,
You can in a way take a HRT test drive, however depending on what effects and how long it takes to observe those effects/changes may depend on your patience. My Endo said something like 5-8 years to see the full effect of HRT on average. Some may take longer, some shorter.
Sort of thing you may run past a therapist first to see what forces are driving you in the first place.
What is generally the most common after effect of a retired HRT programme is the fat redistribution including breast development. So you may wish to take that into consideration.
Hope things work out for you.
Be safe, well and happy
Lotsa huggs
Catherine
