Wishskinny,
I have similar problems when I increase my meds. I have the same symptoms you describe (except for weight gain) plus alot of crying spells. I've had the same results with Levoxyl, Levothroid & now Armour. How long did you stay on your dose when you were feeling this way? I find that I only am really bad for the first few weeks after increasing but then it sorta calms down. I havent reached a high enough dose to get rid of my Hypo symptoms so I keep having to go through it again & again. Right now I'm on 3 grains of Armour and I actually had to go to the emergency room last night I was feeling so bad. They ran lots of tests and I came back perfectly healthy. It has to be the meds causing me to feel this way.
