Great question! Yes, yes, absolutely!
My first six months, I was up and down I really feel it took about six months to feel consistently better and a year for the peaks and troughs to level out. The hardest thing for me to learn was to embrace the positive feelings and use them to sustain me through the inevitable negative times. My default before was much like yours. If I felt great, I feared it as just a precursor to feeling like crap. Changing how i saw the ups and downs was hugely helpful for me.
Now a couple years in, things just don't get to me the same way. Overall I feel about 50 times better than before, all the time. And when something tough happens, it isn't life shattering like before. I just deal with it.
It's a pretty cool way to live, you're gonna love it!
