Hi Donna
I think you already know you have a problem, and really that's all the matters...
The drinking to get drunk, the secrecy, the irritability, the stronger wine, the excuses and downright lies...these are all pretty familiar to me, and they're some pretty good red flags.
Often a Dr's visit - just to make sure all is well - is a good first step... other than that I encourage you to look around, read a lot, post as much as you like.
Most people here use a recovery programme like AA, or one of the others like SMART, and find that very useful - but I have no experience to share there. Others will be along I'm sure
I make a commitment every day not to drink - the good folk here help me to keep that...you'll find a lot of support here...
