But experiences have tempered my optimism... As has it others.
I once bought some highly touted vitamin/herbal supplement that was 'supposed to give me more energy'. This was ages ago and long before PN etc... issues. The smell made me gag, then worse. I was able to get and keep down about 4 doses before I gave up. It was easier on my system to NOT take this 'energy' stuff and just get by..
Turned out my thyroid was seriously outta whack. Meds in prudent doses changed that issue, but it took a few years to get it right.

Starglacier? Could you give us more info about your problems so that maybe the wise folks here could help? There are a LOT of smart folks here who give and share and don't criticise or anything. About anything! While many have strong opinions based on their own experiences, they do understand that your own experiences are not their own. Don't be afraid to ask questions, no matter how silly they seem! No question is too silly! Sometimes those are the BEST ones! And yes, foot drop is a bummer! - j
