Medications for bipolar medication side effect relief

I hope this topic isn't too broad. I thought I'd create a thread about people's experiences with medications that are prescribed specifically to fight side effects from bipolar medications. Please share which ones you've taken and how well they worked, or even side effects from the side effect relief medication(s).

* Synthroid (Levothyroxine) - I developed hypothyroidism from Lithium. The longer I took Lithium, the higher my Levothryoxine dose became. I, personally, never noticed any side effects from Levothyroxine. It only did me good. I currently take 150 mcg

* Inderal (Propranolol) - I initally started a beta blocker to calm tachycardia (fast heart beat). It helped great with that. I also had the added benefit of it later helping ease hand tremor from Lithium. Again, worked well. It is supposed to also help some people at easing akathisia. It did not help my akathisia much at all. I have zero side effects from 40 mg per day (20 morn/20 evening). I usually have perfect blood pressure. I'm not sure if this medication is partly responsible. Seems all good, to me!

* Cogentin (Benztropine) - I was prescribed this to ease past akathisia. It actually did work well, but I had to stop it because it caused me severe constipation. I know others don't get that side effect, though.

* Provigil (Modafinil) - This was prescribed to me when I was struggling with hypersomnia (excess sleepiness). It definitely helped with that, but too much. It made me manic. This medication was attempted on three different occasions (at different times), and all times it eventually made me at least hypomanic. My psychiatrist won't prescribe it for me anymore. I've read that it doesn't make many people hypomanic/manic, so some may consider it. I had no other side effects.

* Ativan (Lorazepam) - Though I used it for anxiety and sleep, at times. My psychiatrist also advised me to take it for akathisia relief. I did for quite a while. It helped, but not all day. It was not an ideal treatment for akathisia, in my view. Also, I became dependent on it and had a hard time being weaned off because of withdrawals. Sometimes I had side effects like sedation or even maybe disinhibition, but they weren't major.

I think that's all of them that I took.
