It took me 4 months to lose 40 pounds, yet I'm not griping. Your weight loss journey is a marathon, not a sprint. Slow and steady wins the race, while fast and crass won't last.
The final result is more important than the speed at which we lose the weight. I've lost 100 pounds, attained my goal weight, and have managed to keep the weight off. That's what's important.
Good luck to you.
