This is really more of a general question. (Mods: if this is in the wrong area please move it)
I'm having surgery in about 2.5 months. To get myself in good health I'm making several changes. While I'm overall very healthy I could stand to drop a few bad habits. First, I have lost about 50 pounds (about 22kg) over the last two years. I still have about maybe 20 that I could stand to lose. Im starting a heavily cardio based workout routine. Due to a bad knee I can't run, but I do have a stationary bike I plan to start putting in about an hour of cardio 4-5 times a week. For anyone who did cardio for weight loss, should I focus on low resistance and speed, or high resistance?
Aside from two social obligations, I am cutting out alcohol completely. If I'm honest, at one point I did drink too much. I've cut it back a lot and aside from the two obligations, I plan to avoid alcohol entirely. My husband no longer drinks so that keeps the temptation out of the house. But, I have noticed I drink a lot more coffee. I try to make sure I get plenty of water too, but I am concerned about overhydration. I pee like crazy now. I know this concern is probably silly, but I never really thought about anything until I started poking around and saw a lot of medical warnings against drinking too much water/fluids.
The last major change is a big one. I have to stop smoking. I've smoked for about six years, with a one year break that lasted until my senior thesis year in 2012. I've been finding reasons to hold off on quitting and I know that's just me being a baby about losing all my vices. But, it's also become a writing aid. My goal is start publishing and I have several projects that are in the works. I had a hard time for about four days motivating myself to write when I stopped drinking (I usually had a glass of wine or a beer when I was writing) and now I take smoke breaks. For anyone who quit smoking, how did you get through the first few days. It's not the physical aspect that I'm worried about, it's the habit part. I don't plan on smoking again and I would like to replace that habit with something less destructive.
A lot of this also came up because I've had some superficial aches and pains that I think was due I dehydration (shallow pains in my muscles) and because I noticed several (extremely tiny) dark veins on my ankles. I checked webmd and let me tell you, it works wonders at scaring people straight.
