Funny...but not...Prozac pissed me off BIG TIME. I simply could not tolerate the feelings of rage and aggression. Neither could those around me=)
Yea, I understand about the holiday foods, too. I always eat my weight in sausage balls and wedding cookies, Claxton fruitcake, Cella cherries, Terry's chocolate oranges, firecrackers, etc. etc. Those "special" foods are going to fluctuate my weight 5 to 7 lbs., but it comes off when my gluttony is halted.
Our age is definitely a factor as well...no matter how disciplined our diets. I don't obsess about my weight, because I maintain a constant jean size. I do resent the obvious SE of some meds, though, that have the potential to turn a bean pole into a pylon.
My Zoloft was increased to 150 mg several months ago. I'm also trying to navigate PM, with no end in sight. The added frustration of KNOWING "this is as good as it gets" (and it's BAD, trust me) is mind-numbing. Now, with 7+ months of SHINGLES in my face and eye/scalp, I'm FORCED to take Neurontin. I despise the effects of this med, but it holds the hemlock at bay, for now.
I know..."enigma". I'm choking on the mere thought of a "new" year. Sorry, y'all. I swear I'm TRYING!
Powdered Sugar-Coated HUGS to all!
