I wish you the best on getting off your plateau. I hit a plateau for a week and I stepped up my workout - that seemed to have worked for me.
WOW - What a personal trainer!
Do you have a nutritionist, too - or does the trainer talk with you about all that stuff?
I took ephedrine (it was in my Xynadrine) - it worked but when I quit taking it - it threw me into depression. I will never take a pill to lose weight or to jumpstart it again. I just wish you the BEST in what you decide to do!
I'm glad to see that you talk with your doctor about everything you do - that is a way to keep it safe. BEST WISHES!
