Hi Meg and welcome.
"I have all kinds of emotions right now...Part of me is SUPER motivated, and another part of me is so sad that I'm going to have to rethink my unhealthy COMFORTABLE habits..but it needs to be done!"
I gained 60 lbs. in 2005 from a medication that I stopped in 2006...and then set out to lose the weight on the Atkins diet, which I'd been very successful with back in the 90's (and then had maintained for 12 years). However, I was so horrified by the weight I was gaining from the medication, that I ultimately almost stopped eating altogether and mainly drank coffee, which I have always loved. BUT...for some darn reason, I began to put more and more artificial sweetener in it...and am even too embarrassed to tell you how many I was putting in my coffee...it was probably a dangerous amount. SO....I could not get the diet to work and was beyond frustrated for several years...getting nowhere.
At any rate, I finally had them trouble-shoot for me on a different site and it turned out that the artificial sweeteners were causing the diet not to work for me this time around. But THEN....I felt exactly as you did....horrified and scared that I would have to give up my ultra-sweet coffee...which had become the highlight of my day. (turns out I can have up to 3 packets of Splenda max...a mere fraction of what I used to use)....BUT, all my fears and apprehension turned out to be silly.
Yes, there was an adjustment period for a few days but I quickly learned to adjust to the much less sweet coffee and in fact, it now tastes perfectly sweet to me with only one packet of Splenda per cup...3 cups/daily total....and I can't even imagine how I drank it with so much sweetener in it.
So don't worry...this is normal. Just maintain a state-of-mind that this will be much healthier, will have huge benefits and that although you may have a short adjustment phase, that if you stay strong and stick to it, your taste buds and your preferences will completely change and you can come to love and prefer an altogether different...and healthier..eating plan.
Plus...I can ASSURE you now....NOTHING ever tasted as good as being a normal weight now feels.....trust me!
It's totally worth it.
