I have been using the tablets since
early 2013. However, after stopping the
patch, I used a different form which got my
estrogen level up. I then switched to the tablets which do a good job of maintaining my level.
It is hard to say if you are getting too much or too little since symptoms can be similar. However, I have read that the patch does a poor job of "filling up" the estrogen tank so to speak. So if your level is low, it may be impossible to get enough with the patch.
