That's almost EXACTLY my weight loss for Jan-March as well! I think it's great! It's gonna take time but slow and steady wins the race. Just keep doing these things - if the scale goes down, then you're on the right track. If your pants are loose, you're DEFINITELY doing something right.
15 pounds in 3 months is 5 pounds a month - think of it, in one year you'll be down 60 pounds at that rate. Even if you don't, you can still lose 50 pounds in a year or 40. That's a lot!

But day by day, it's gonna go a little slow. I'm sitting at a very annoying "plateau" right now (weight yo-yoing like mad - water and swelling and forgetting to eat dinner playing a big part) and averaging right at 150, which is frustrating!
But I'm keeping at it... going to gym... being gentle with myself as I recover from injuries because this is for the rest of my life, not just to lose these 40-50 pounds... and if I lose slow right now, then at least I weigh SOMETHING less at the end of the month.
I try not to be jealous - instead, I just look at how far I've come and look forward to the road ahead. Think of how many people say they'll lose 15 pounds for their New Year's Resolution and never do it. You knocked it out in the first 3 months of the year! You're doing great
