I'm happy you are back and ready to start fresh with your recovery. Right now might be a really good time to look at what you were lacking in your recovery plan last time. Filling in the gaps and weak spots will be extremely important for this time around. Also, listing numerous ways to handle stress in a healthy way will be beneficial so this time around will be different.
Happy to hear you are going to a meeting this evening- we can't do this alone...we need a sober support system that we can lean on and connect with when we are having weak moments.
As for ways to get through withdrawals easier- as said above there is no magic pill to get through them. You can make an appointment with your doctor and he or she can evaluate you and decide if there are any prescription medications that would benefit you in this time. Ashwaganda (at GNC) is good for mood, energy, anxiety, and overall mental health. St Johns Wort is a natural anti depressant and Melatonin is a natural sleep aid but before you take any supplements please talk to your doctor since supplements interact with many medicines and can have negative side affects if you have certain medical conditions. Creating a sleep routine, being active and working out- even if you are just taking short walks it will help with endorphins, meditation, yoga, journaling, etc. are all good ways to get through withdrawals also.
You can do it!
