Gosh I think that is really poor advice about not weaning off, even just by doing alternate days then every three days etc. Rebound acid is a known thing when stopping these meds so I'd definitely go slowly. If you take one tonight, perhaps also take gaviscon advance right before bed and prop yourself up a bit (I bought a wedge pillow from amazon which did help a bit) and I'd do daily now until the burn goes (so you don't hurt your tummy lining) then try alternating days. Are you on lowest dose available of the ppi? When I was researching how to come off it safely, forum users were talking about breaking open the capsule and taking a small amount out each day so your body gets slowly used to having less. It can be prescribed in capsules, tablets or liquid so perhaps you could ask GP for liquid or capsule if you've been given the tablet form. Even the NHS website says that symptoms may come back if you stop suddenly and if you have been on them a long time then you may need to come off them gradually.
