I guess it depends on whether or not you cosleep. My kids were in their crib, so when they woke in the middle of the night I would send my husband in to calm them and get them back to sleep. If I went in, they would want to nurse-and scream until I gave in, but if I sent my husband in, they would calm right down and go back to sleep. Also, if you are still putting him down asleep at night, you want him to learn to self soothe, so you need to start putting him down awake. For my son we ended up doing a modified cry it out at 7 months since I had been back to work since he was 6 weeks old and the waking 3 times a night to nurse was taking its toll on me. It only took 3 nights for him to get the idea and after 1 week we had no more night waking. My daughter was much easier. She weaned herself of the night wakings at 3 months old, and we never had to cry it out. She was always a better sleeper than my son (still is). We waited for a weekend to start with my son's sleep training so if it didn't go well at least we could try to nap during the day. Since he is only snacking when he wakes it sounds like he is using you as a pacifier. If he already takes a pacifier, the night wakings may be as easy as your husband going in and putting a pacifier in his mouth. When we did it with my son we tried not to pick him up when we went in there in the middle of the night, so we soothed from the side of the crib, put in a paci, rubbed his back, turned his music on, etc. Like I said, it went way better than we expected. Keep in mind though that you will still have setbacks, especially during teething outbreaks, illnesses and growth spurts etc. My two year old still occasionally wakes up when she is sick, and I never leave her if I know she doesn't feel well. Once you do this you may have to break the habit when they are feeling better, which at two, can take a couple of days since they are much more stubborn at this age, but they get back on schedule pretty quick. Good luck. There is nothing better than getting a full nights sleep after going without for so long. Once my son finally started sleeping through the night it took me over a month to do so myself since I was so used to getting up several times a night. When I finally got that full night's rest I felt like superwoman the next day. It's amazing how good sleep can make you feel.
