Minor things set me off into a full on panic attack. I’ve had them and been treated for them before–then quit treatment and drank to keep them at bay.
Withdrawal from anti anxiety/depression meds made me never want to go back on them again. I am going at this by changing my diet and exercising. I know 5 days in is early but good God this is hard. I feel like I’ve been working at being sober for months, not 5 days. Er, 5 and a half days 
Yes it does get easier. It does feel like you have been trying to stay sober for forever at first and I used to get major panic attacks during the first few weeks. You just have to remind yourself that this is all normal behavior during early sobriety. When a panic attack hits me I just let it hit me and tell myself I’m gonna be okay and this is just my body readjusting back to a normal state of mind. 
In short, yes it does get easier. I would really recommend meditation to help with the panic attacks… if you haven’t meditated before or don’t think it’s for you try a guided breathing meditation CD or yoga nidra on YouTube 
It is like some weird science experiment.
Life flies by when all you live for is booze.
You stop drinking.
Day one sober feels like a year.
Day two seems like 11 months, 3 weeks.
Etc.!
And then, after a month or so, a day feels like a day again, just a day where you get a shed load more done than ever before!
Thank you SO MUCH everyone for your replies. It helped me to keep my sanity today.
