I'm finding the otc GABA, L-Theanine gummies (Olly brand) definitely take the edge off of the anxiety and fast heartbeat I've had from taking corticosteroids. It's nothing like prescription strength meds and what I was trying to avoid so I'm happy with this.
ALSO, the Topamax is working great. Not only have I just had two very mild migraines in the past month compared to the usual 7-9 with a couple being really bad, I'm experiencing much milder Fibro aches and pains as well as less fogginess. I wish I'd heard about this medicine sooner. I'm still on Tramadol and getting off will be chore, that will have to wait until I'm clear of PMR. One major thing at a time.
