Hi, I'm a retired teacher who was subbing for ESS, but insomnia and other withdrawal symptoms aren't predictable enough to allow for scheduling jobs. I had to arrange to take January off and hope to be able to get back to work in February. It's iffy. I believe I know in some part how you feel - it's very frustrating not to be able to do something that you've previously done, but need to continue doing. Teaching is challenging enough without all the other miseries caused by withdrawal. You do need to slow down the process as Sandi said. I went off too quickly (doctor didn't know how to safely guide my withdrawals either) and the withdrawals were not good. Maybe you can level out to a place where you can still work and yet begin to get off slowly enough to help with your other health issues. I'm trying diet, exercise and prayer - hang in there - it will get better.
