Hi Liz,
I agree with Josie. Sit back and enjoy the ride. For myself I too felt good when I started. Once I told my doctor and started doing this right I felt positively giddy. Since then I've come down to earth more and have indulged in second thoughts and doubts yet though it all I've never lost the feeling that I am doing the right thing.
I hope your bubble never pops.
Hugs,
Jeanette
