Finally starting to feel better

I'm going to start this by saying I'm also 5'2 and started at 211 lbs in June of this year. When I first started MFP it gave me the generic 1200 calories a day. By the end of the week I threw that out the window and upped my calories because I want to sustain a healthy diet while losing weight.

My first thought reading through your post is that you're probably eating 1200 or less calories a day, because when you undereat like that, you WILL feel like crap. You don't have any energy and you're lethargic.

My Second thought was, oh great, here we go again with the supplements. I had to look this one up, since I'd never heard of it, and wow... the contents....

Chromium (which is a metal) 200 mcg... suggested dosing for Chromium is 30mcg. Per webMD, Some people experience side effects such as skin irritation, headaches, dizziness, nausea, mood changes and impaired thinking, judgment, and coordination. High doses have been linked to more serious side effects including blood disorders, liver or kidney damage, and other problems. I'm not sure how much is a high dose, but this doesn't seem "win" to me.

Selenium 90 mcg. Daily recommended does for adults is 55mcg. Per webMD, Selenium is LIKELY SAFE for most people when taken by mouth in doses less than 400 mcg per day, short-term.
Higher doses are POSSIBLY UNSAFE. They can cause significant side effects including nausea, vomiting, nail changes, loss of energy, and irritability. Poisoning from long-term use is similar to arsenic poisoning, with symptoms including hair loss, white horizontal streaking on fingernails, nail inflammation, fatigue, irritability, nausea, vomiting, garlic breath odor, and a metallic taste.
Selenium can also cause muscle tenderness, tremor, lightheadedness, facial flushing, blood clotting problems, liver and kidney problems, and other side effects.
There is concern that taking selenium for a long time might not be safe. Long-term consumption of selenium supplements appears to increase the chance of getting type 2 diabetes. It also seems to increase the risk of skin cancer recurrence. There is also some concern that having too much selenium in the body might increase the risk of overall death as well as death from cancer.

Vanadium, 25mcg.
People get vanadium from food and from supplements. An average diet provides 6 to 18 mcg of vanadium per day. The various vanadium supplements contain a different amount of vanadium, depending on the chemical compound used. For example, vanadyl sulfate contains 31% elemental vanadium; sodium metavanadate contains 42% elemental vanadium; and sodium orthovanadate contains 28% elemental vanadium.
The National Institute of Medicine has set the tolerable upper intake level (UL) of vanadium, the highest intake amount for which no unwanted side effects are expected, at 1.8 mg per day of elemental vanadium for adults. No UL has been set for infants, children, and pregnant or breast-feeding women. In these groups, vanadium intake should be limited to food or infant formula.
Vanadium is LIKELY SAFE in adults, if less than 1.8 mg per day is taken. At higher doses, such as those used to treat diabetes, vanadium frequently causes unwanted side effects including abdominal discomfort, diarrhea, nausea, and gas. It can also cause a greenish tongue, loss of energy, and problems with the nervous system.
Vanadium is UNSAFE when used in large amounts and for a long time. This increases the risk of serious side effects including kidney damage.
Vanadium might lower blood sugar. People with diabetes should check their blood sugar carefully and watch for signs of low blood sugar (hypoglycemia).


And then there's the usual suspects like different caffeines, green coffee bean, etc.

So yea... all sorts of win. NOT.
IMO, eat a healthy amount of food, within a sustainable caloric deficit, and you'll probably feel 100% better and you'll be happier and healthier. Also, research the supplements you're planning on using.

Just my two cents.
