Doxycycline Hyclate and water weight

I am 40 years old and I haven't taken an antibiotic since I was in my early 20's. I was given this drug after an outpatient surgery.
I am on the 4th day of a 6 day perscription and I have been suffering from a burning in my stomach, I am freezing and it's 65 degrees outside. I have gained about 6 pounds of water weight, I know it's water weight because my feet are fat. I'm normally 115lbs, so I do not have fat feet.
The worst physical side effect is the bloating in my stomach. Although I haven't experienced any nausea, I absolutely do not want to eat because the Doxy makes my stomach feel like I swallowed a rhino any time I eat anything. However, I swing between not being hugry at all and wanting to eat everything in my house.
And if I hadn't entered this site I would have never figured out why I'm so damned depressed! I'm not moody by nature so there's no way I just decided to suffer from depression for the hell of it. I was cracking jokes before, during, and after my surgery. Today I feel like crawling in a hole and dying but I'm not suffering from any post-surgery pain! I hate this drug!
Oh, yeah, I also can't see very well, blurred vision.

I've never skipped a period in my entire life. In fact, I've only been late by a day or two once about 10 years ago. I started taking doxycycline for acne about two weeks before I should have gotten my period. One of the common side effects I wasn't told about? "Menstrual irregularities" and "irregular uterine bleeding." It stopped my period entirely, caused lower abdominal cramps and water weight gain. I have been seriously uncomfortable for over a week now and am waiting for my body to balance back out after taking this drug. As a sidenote: This antibiotic also causes birth defects, vaginal itching, yeast infections, seizures, hormonal fluctuation and depression.

I was prescibed it in the form of periostat, for Rosacea. It has worked very well at reducing it by about eighty percent. I use it with Rosac cream a sulphur based cream. The antibiotic has blown me up with water weight and I have experienced terrible moods, depression and dry hair also ringing in the ears...I am counting the days till I am finished with this horrible medication it also makes me feel "out of it" and strange.
