If it's really severe, then snoring is not a joke, it raises the risk of all kinds of horrible things. My husband was a snorer, really bad, and I would hear it stop, then start with a really loud snort/splutter. I managed with ear plugs, sleeping separately for a while (much better than keeping two people awake, especially if with a small child). Moving position didn't make any difference, so giving him a shove was more out of my own annoyance than anything and not acceptable for him when he couldn't help it.
In the end, he had three sleep studies (one showed nothing, but that is because the NHS is crap, I knew he had sleep apnoea). He had terrible sleep apnoea and his oxygen levels were very low at night, so he now uses a CPAP machine. The NHS won't give you one just for snoring, but you could try getting one privately, or if you think he has sleep apnoea, definitely go to the GP and ask firmly for a sleep study, don't be fobbed off with 'lose weight' as people with sleep apnoea are so tired, they often find it difficult to exercise anyway.
The pills are a diversion, because I am not sure what kind of pills cure snoring (it wasn't one of the options we ever were offered). He may not like taking them if they make him sleepy the next day. Usually the choices are surgery, one of the over the counter remedies (nasal strips) or a CPAP machine, or simply adjusting your life to accept he snores, so buying a proper bed/sofa and planning to sleep on it/him to sleep on it half the week.
Poor sleep is terrible for everyone, but I can't believe how many people moan about it, but don't do simple things like get two duvets, see the GP, sleep in separate rooms part of the time or get ear plugs. Prodding him all night every night is not a solution.
