I am glad you wrote what you did. I just looked at my post and it just seemed to sound more cold than I meant for it to. Good job on your post, it was helpful and kind. I remember those days with little ones running around - how precious those memories are now.
As for starting the medicine, if you can't wait for an appt. I'd at least call the doctor and verify it's okay, so that he/she is caught up on what treatments you are using and approves of it (can alert you of any issues he/she might expect based on your updated life circumstances or other medications you may be taking). I am not sure if your doctor will do this, but sometimes my doctor or nurse will give me this kind of advice over the phone, especially if I have seen them recently or for the same thing in the past. Sometimes though they want to see me first. If your symptoms have gone away and come back it's always good just to get checked out to make sure there's nothing "new" going on, just in case.
But to build on what bbxx said here's an idea if you can manage - I have 2 kids (7 and 2). I found a health club nearby that offers exercise classes, weights, treadmills etc. and a pool, spa, sauna, hot tub. It ALSO offers childcare for 3 mos old + for up to 2 hours daily, and the kids love to go there and play. Plus it's pretty affordable. I'm not a huge exercise fan but I know I should do it :) So I'll go over there and take a yoga class, or if I don't feel like it I won't even exercise, meet a friend in the cafe, or sit in the hot tub a while, if I can afford it get a spa treatment, knowing that the kids are being watched, are in the same building and are having fun. Or find a friend with kids and meet and let the kids occupy each other while you chat. "Time off" from being mom is something I never EVER used to take (and still have trouble doing) because there's nothing I love better than being a mom. However, I have learned to really appreciate it , even if I take it in small chunks, because it really helps me personally deal with stress and anxiety just to have a few minutes to myself to think and breathe when I'm feeling really wound up.
Anyhow it's just another idea, maybe something that will help tide you over til you can get in to see the doctor.
Oh boy, I do hate to see you up your meds if you can live without it. Is there any way that you can instead perhaps get a massage once a week or do something relaxing instead of taking more meds? I like to remind people that these drugs are not candy and can in some cases cause damage when you try to get off them or when you are on them. I remember having little ones and all moms are stressed during that phase. Only you know if you are stressed in a way that would be a danger to yourself or your kids, but if its only some tension in your neck, I would love to see you try other therapy first. :)
