It's very likely the side effects of one of your medications. I'd discuss that possibility with my psychiatrist if I were you (particularly the restless leg condition).

It can also be caused by foods in your diet, strangely enough. I often wake up in the morning feeling great only to have the feelings dissipate after breakfast foods or luncheon foods that could contain "fast foods". And part of it is the acidic buildup of residue (or ash) caused in the digestion of medications.

Try using the lemon thing to remove that late in the afternoon; that might give you some relief. You know the "lemon thing": squeeze two fresh lemons into about 5 oz. of water; drink it. If you aren't better in 4 hours, repeat the process. It might work for you; it does for some of us. Give it at least two days before you resign yourself to the idea that it won't work for you. It takes a while to dissipate that acid from your fluids and tissues.

Some people use Alkaseltzer and that might work, but for those who have high blood pressure,
it would be precluded because it contains sodium bicarbonate. It's not as healthy for
us as the lemon is, anyway. (The lemon is a strong detoxifier of the liver which is responsible
for removal of many toxins from the system; medications can be toxic in one way or another.)

If it does work, use it thereafter only occasionally when you feel the bad feeling tones
creeping back.
