1. How worried should I be about my potassium intake?
Not very much, on average. Some people need to worry about it more than others, but in my experience, there are only a few that need to limit their potassium significantly.
2. How common is potassium in a normal diet? I've scanned everything in my kitchen and the only things I've found potassium in is peanut butter and certain cans of beans.
Common enough. Bananas are infamous for it. Worry about it if your doctor tells you to.
3. If a food product contains potassium is it required to be on the Nutrition facts label?
No idea. A lot of food with potassium in it isn't labelled anyway, such as loose fruit. Potassium is usually labelled, though.
4. I have read that I should add more salt(sodium) to my diet while on spiro. Is this true? If so, how much should I add without over doing it?
You should add as much as you feel like. I let my cravings guide me here - if my body really really wants sodium, then it's probably a good idea to let it have it. It would be unwise to add more than I crave, I feel.
5. I have also read that exercising(sweating) is a way for your body to push potassium out of your system. Does spiro affect this process?
I'm not sure. You'd have to ask the doctor, but hopefully you won't need to exercise just to maintain your potassium levels.
6. If anyone here has a certain diet aimed at limiting potassium intake, mind sharing it?
Your doctor will tell you what foods to limit if it becomes an issue. I don't follow a specific diet, personally.
9. How long into taking E are the emotional/psychological effects noticeable?
Immediately, if you count placebo. The emotional effects typically take place as one's depression and/or dysphoria starts to lift, which is generally either right away or when the physical effects start to take place. Generally, this just relates to being a happier and freer person. However, I notice that it's easier for me to cry even though I'm in a nearly identical emotional state as in pre-HRT - so I figure that comes on hormones somewhere along the line. That'd be anywhere up to a year, if my experience is typical.
10. Is DVT/PE a major concern while taking estradiol(estrofem)? If so, what steps do you take to prevent it?
If you don't smoke, and you're under 40, it's generally only a concern if you overdose.
11. Is it ok to take vitamins and/or supplements during HRT? I currently take omega 3 and plan on taking a multi vitamin. Could these impact my progression or health?
They do impact your health. In a positive way - keep taking them, unless your doctor becomes concerned for whatever reason.
