So I decided on week 3 that I'd order another 2.5mg pen as the side effects for the first 2 weeks were horrendous. However, on week 4 my appetite was definitely back and I didn't really feel any effects so I worried I'd made the wrong decision. Anyway - I took my first dose of my new pen 2 days ago and I feel awful and the sulphur burps are back! Is this a bit weird?
